Over the past few years, we have seen a massive surge of video games that push the limits of both our systems and how much a video game can truly offer players. Games can now offer players tons of quests, miles upon miles of open ground to cover, and gameplay that can last hundreds of hours. However, with so many great games releasing  it can be hard to just buckle down and finish literally everything in a single title.

When determining this list we decided to not just limit it to the size of the title’s world, but also to take into consideration the number of side activities offered beyond just quests. We also decided to look at modern games only, since most retro titles would just fill this list on their own. Finally, we are going to remove MMOs as those also offer a near endless amount of gameplay with no real discernible finish. Yet, if you are looking for a new game to play, you might want to set aside a few hundred hours for these.
Skyrim

Out of all the Bethesda games, Skyrim is perhaps the biggest thanks to the number of things to do outside of the main quest. Not only are their dozens upon dozens of side quests to complete (most of which are more than just one step), but Bethesda has hidden so many extra tasks for you to complete. You can hunt all of the wildlife, raid every tomb, buy and build every house around the kingdom, or just read the crazy amount of books to further your knowledge of the world.
Hell, just trying to find all the books is a monumental task that could eat up hours of your life. Yet, it is possible to 100% Skyrim, even if you’ll be as old as a dragon by the time it’s all over.
The Witcher 3: Wild Hunt

The Witcher 3 is perhaps one of the best games ever made and a lot of that has to do with the sheer volume of things you can do when exploring the world. Not only does The Witcher 3 have some amazing side quests, but many of them can take anywhere from 30 minutes to a few hours to fully complete. This, of course, isn’t including the absurd amount of locations, treasures, and bandit camps that you will need to raid.
Oh, did we mention harvesting materials, hunting down manuals, and crafting several sets of Witcher specific armor? Plus. there is the surprisingly captivating mini-game Gwent where you will need to play every NPC merchant, collect all the rare cards, and what do you mean it’s 4 in the morning and I have work?
Grand Theft Auto V

Grand Theft Auto V is one of the most popular games of the modern era, most of which is thanks to the amount of time a single player can invest into its world. Outside of just completing the main story, which can easily add up to 40+ hours of your life, GTA V is filled with a plethora of side activities and events that you can take place in. From buying all of the clothes in Los Santos to a few rounds of golf and even taking some flight classes can greatly expand this title’s length.
Not to mention the wonderful GTAÂ Online mode which has been constantly updated with new content and expansions that have kept the multiplayer quite fresh and entertaining.
Diablo III

While the campaign for Diablo III is relatively short, it’s the post-game activities that will keep you busy for weeks on end. This is thanks to their randomly generated dungeons known as “Nephalem Rifts” that are full of interesting enemy combinations, bosses, and, of course, loot. If you want to collect everything in Diablo III, there are dozens of armor sets that you’ll need to snag along with all of the individual legendary gear.
Then there are Diablo III’s Seasons which are 2-3 month events that can offer exclusive rewards and cosmetic items. If that’s not enough you can always try to complete all of the Seasonal challenges and Set Dungeons that are incredibly difficult. If you want to truly finish Diablo III you will need to slay thousands of hellspawn.
No Man’s Sky

It shouldn’t be any surprise to see No Man’s Sky on this list since it is the biggest game ever created in terms of sheer volume. With trillions of planets to explore it’s essentially impossible to see  everything that this title has to offer, especially since you can name all of the fauna and wildlife you discover.
Even with the massive drop rate of players, visiting every planet (discovered or not) will never happen. No Man’s Sky is a game that really doesn’t have an ending and it’s just an endless loop of exploration and discovery.
