10 Open-World Games That Have Over 100 Hours of Playtime

There comes a time when you may just want to sink over 100 hours into a single game. This happens to me a lot, and the genre I always find myself returning to when I have that urge, is open world. The massive maps that these games offer, with long adventures and tons of side content to complete, and a true sense of discovery found in exploration is unmatched.

The games mentioned in this article are difficult to put down due to their addictive gameplay loop, engaging mechanics, and content that constantly pushes you forward to a new objective. Time flies by when you play these games, that before you know it, you're way past the 100-hour mark.

It's important to note that this is not a ranked list and these games are in no particular order. This is meant purely to inform you about games that are hard to put down, due to never running out of stuff to do. If you're a completionist looking for a game that you can really sink into, and spend weeks playing, then this is the article for you.

10 Starfield

Journey Through Space

Love it or hate it, Starfield has tons of content that can last you way past the 100-hour mark. Not only does the game offer tons of main quests and side missions, it also has a very in-depth ship building feature that can keep you hooked for hours on end. There's no better feeling starting from a low-tier ship, just to build it up to something straight out of Star Wars, and then taking it into space to raid enemy ships and take their loot. It truly is a great time.

Starfield offers more than just quests and ship building, however. It allows you to roleplay in unique ways, such as romancing different companions. You can also join factions or become enemies of them, adding a ton of immersion to the game as you open up new storylines and interactions with others. While it's not the best Bethesda game out there, it still has their DNA written all over it, and brings the type of depth you would see from the developers' other games, like Skyrim and Fallout. If you're someone who ends up actually liking Starfield (I'm one of them), then you can expect a game that provides more than 100 hours of playtime.

9 Assassin's Creed Odyssey

A Long Journey In Greece

Assassin's Creed Odyssey is a fantastic game, one of the better ones in the franchise, but it's also the entry that made Ubisoft known as the developer that adds way too much bloat to their games. The map of Odssey is absolutely massive, filled with various points of interest, characters to meet, side quests, forts to clear out, bounties to complete, and much, much more. It's a game that is so filled to the brim with content that it can sometimes feel overwhelming, to the point of exhaustion. However, it's a game that players can always return if they're bored for more hours of play, which is always great to have.

If you're someone who likes to go down a checklist, completing various tasks, with tons of waypoints and markers, Assassin's Creed: Odyssey is a good choice. In fact, all Ubisoft games are a good choice for you, considering those features are their bread and butter. In AC Odyssey, you won't ever be left with no content to complete or places to explore, unless you have the determination to put in 150 hours, which, according to How Long to Beat, is how many hours it takes for completionists to do their thing.

8 No Man's Sky

Procedurally Generated Planets

No Man's Sky is arguably the most unique choice on this list, mainly due to its procedural generated planets, a mechanic that increases its playtime to way over 100 hours. Players can expect to spend hours upon hours discovering new planets they have never seen before, each time they load into the game, and that sense of discovery really drives the player's motivation to keep playing. The greatest part about this game is that there is no mandatory way to play it, and your experience may be completely different than others. It all boils down to the player's imagination.

Whether you want to focus on the main missions, exploring, building settlements, farming-specific resources, take care of your spaceship, complete odd jobs for money, and so on. It's a giant sandbox that is constantly surprising you, and constantly wanting you to play more. When No Man's Sky first released, it didn't do very well, but the amount of work the developers have put in has made it one of the most addicting open world games to date. Just be prepared to focus

7 Metal Gear Solid V: The Phantom Pain

Kojima's Longest Adventure

Metal Gear Solid V: The Phantom Pain is the largest Metal Gear Solid game to date, featuring an open world filled that is explorable in its free-roam mode. Besides its lengthy main quest, which can take close to 50 hours, players can spend their time completing side operations that offer valuable rewards. Unlike other open world games, where players can accept many side quests whenever they feel like it, players need to progress the main mission in order to unlock many of the side ops in Phantom Pain.

Since players unlock side ops as they progress the main story, and since they offer such valuable rewards, this generally leads to the average player sidetracking to complete them. So, if you add up the time it takes to complete side ops while completing the main quest, then you're looking at an experience that takes over 100 hours. Additionally, the game features in-depth weapon customization and upgrading the Mother Base, which involves gathering the correct materials, adding even more time to the overall experience. Completionists should expect to spend 150 hours or more to do everything.

6 Death Stranding 2: On the Beach

Become the World's Best Delivery Man

The original Death Stranding got a mixed reception by fans and critics when it launched in 2019, with some players absolutely hating the delivery system gameplay, while others fell in love with the relaxing and cathartic vibes that it offered. Personally, I adored the original Death Stranding as it offered a unique experience that was different than everything on the market. Its sequel, Death Stranding 2: On the Beach, is an even better experience, offering the same gameplay loop but with more activities to do and a more refined experience. Delivering packages has never felt so good, and since its mechanics are so streamlined and user-friendly compared to the first, players can spend over 100 hours due to the addictiveness of it all.

While the main story will only last you around 40 hours, which is a great length in and of itself, players who want to connect the entire Chiral Network and complete all deliveries the game offers can expect to spend triple that amount. Unlike the original, Death Stranding 2: On the Beach offers two large maps, instead of one, that offer a considerable amount of activities to complete, sights to see, roads to rebuild, trams to construct, and more. Add on the fact that the game offers a ton of unlockables, such as costumes, tools, etc, and you have a game that takes forever to officially complete.

5 Red Dead Redemption 2

Take on the Wild West

Red Dead Redemption 2 is essentially just Grand Theft Auto in the Wild West in terms of gameplay, but it has a much better story and characters overall. Similar to other RPGs on this list, RD2 doesn't put many constraints on player agency and pretty much allows players to do whatever they please for as long as they like. Want to go to a bar, get drunk, and start a fist fight? That's possible. Or maybe you want to tie someone to your horse and ride them around in a merciless way. That's another crude but very enjoyable thing you can do. These are just a few of many examples of hilarious activities you can do.

My point is: there is so much random stuff you can do in Red Dead Redemption 2 that gives the player over 100 hours of playtime. Outside strange activities, players can expect the main quest to last around 60 hours, and an additional 31 stranger side missions to complete, which will take nearly the same amount of time. Red Dead Redemption 2 is one of those games where you continuously find something new to partake in, and since it's all grounded in fantastic gameplay, there's no limit to the amount of hours it may take you until you stop playing.

4 Kingdom Come: Deliverance 2

One of the Most Immersive RPGs

Kingdom Come: Deliverance 2 is one of the most immersive RPG's to date, and it's clear why it received a nomination at the 2025 Game of the Year awards. Its immersion lies in the true consequences of your actions that can change your playthrough, having to cure hunger and sleep, and a reactive world that can be completely different from other players. It's the true definition of an RPG and one that has over 100 hours of playtime if you're looking to explore the entire map and complete everything. Personally, I spent 140 hours in its world and still was finding new situations to get myself into.

Besides completing the main quest, which can take upwards of 60 hours, players can expect to get sidetracked with other activities such as sword competitions, blacksmithing new weapons, gathering herbs and other plants for alchemy, competing against NPCs in Dice, and just exploring the vast world filled with characters that have their own personalities and daily lives. Each character you interact with can lead you to a new side quest or mini-storyline to engage with, showcasing the shocking amount of detail and work that went into this game. Kingdom Come: Deliverance 2 is a game made with care, and you can easily tell by the sheer amount of worthwhile content.

3 Cyberpunk 2077

Take a Step Into the Future

Next up we have another CD Projekt Red game, Cyberpunk 2077. If you aren't aware, which I'm sure you are, Cyberpunk 2077 released in a completely broken state, to the point that it was so bad that PlayStation actually started issuing refunds. No one could play it because it simply was not finished. Fortunately, after years of dedication and hard work, CD Projekt Red has fixed all its issues and the end result is one of the best RPGs to date. It features a world that feels so alive, filled with activities and quests to complete, and an endless amount of content that will keep you hooked for way over 100 hours.

Not only is there a vast city to explore in Cyberpunk 2077, but it also offers an in-depth build customization system that is a ton of fun to mess around with. Taking the time to come up with different combinations of abilities, such as hacking, slow-motion skill, invisibility, etc., is super addicting that it alone can increase your playtime. Additionally, there are contracts, side jobs and gigs, the opportunity to romance characters, gain XP to reach max level, and much more. Even better is that its DLC, Phantom Liberty, made the game even larger and added another 30 or so hours.

2 The Legend of Zelda: Tears of the Kingdom

This Sequel Is Even Bigger

2017's The Legend of Zelda: Breath of the Wild was Nintendo's first attempt to put our favorite hero into an open-world formula. Not only did Nintendo absolutely nail it, but they influenced the genre in many ways and inspired other developers to follow suit when it comes to exploration and discovery. The Legend of Zelda: Tears of the Kingdom, the sequel that released in 2023, is a bigger, bolder version than the original. While Tears of the Kingdom takes place on the same map, there is way much more to do due to its complex physics mechanics and points of interest that can be found in the sky.

Similar to the original, Tears of the Kingdom follows the shrine formula, where players can discover over 150 shrines scattered throughout the world, each offering their own puzzles, rewards, and secrets. Outside of finding these locations, there is the main quest, side quests to discover and complete, armor to find, hidden locations, and much more. Completionists, who enjoy doing absolutely everything a game has to offer, can expect to spend upward of 200 hours. Especially if they decide to find all the Korok Seeds, which there are more than 800 very well hidden throughout the incredibly large map.

1 Elden Ring

Become the Elden Lord

Elden Ring, FromSoftware's magnum opus, is an experience that will go down in history as one of the best games ever made. Not only for its sheer scope in size, but its sense of discovery and the amount of secrets players can find is so incredible that it pushes the genre to new heights. With almost no waypoints or quest markers, players are left with their own sense of curiosity to go off on an adventure to see what they can find. It's because of this lack of guidance that players can expect to spend over 100 hours in one playthrough of Elden Ring, and arguably even close to 200 hours with its Shadow of the Erdtree expansion.

There are hidden locations, such as caves, catacombs, and even an entire underground city, that players may completely miss if they aren't observant enough. Side quests can be started by finding hidden NPCs, who gives almost zero information on how to complete their task, leaving the player to use the ole noggin to figure out how to complete it. Discovering secret locations, finding hidden bosses, and completing vague questlines, on top of the main story, will push the player's playtime into the triple digits. Even when you think you've exhausted everything to do, if you explore enough, you'll stumble onto something new in Elden Ring.
