There's no doubt about it: some of the best video games in existence have one major flaw. They lack co-op capabilities. Open-world games have redefined the way people think about gaming and the ways in which technology can immerse you within your own living room. These boundary-pushing experiences, however, lack the social benefit that comes with playing co-op.

Sure, you can text your buddy about how you beat that Lynel in The Legend of Zelda: Breath of the Wild's Hebra Mountains, but it's not the same as joining forces and actually defeating that scary centaur creature that shoots lightning bolts from its bow together. A player can dream, though, and that's why it's worth fantasizing about the top single-player games that would benefit from adding co-op. So, go ahead and whistle for Epona or power up your Pip-Boy. It's time to team up and beat up some bad guys.

10 Grand Theft Auto 5

Pulling off heists is best done with friends, and Grand Theft Auto 5 offers a perfect missed opportunity for some serious co-op action. Although an online component of the game does exist with GTA Online, the campaign's version is single-player only. Set in Los Santos (a fictional version of Los Angeles), the game's plot follows three characters intent on moving up within the city's criminal underbelly.

With its open-world setting, you can explore just about everywhere while stealing cars, attacking enemies, and causing general destruction and mayhem on every corner. Co-op would let you get even more creative with completing missions since other players' decisions could impact the outcome. And hey, if you end up being marked as "Wanted," at least you won't be alone.

9 Red Dead Redemption 2

Arthur Morgan On Horseback in Red Dead Redemption 2

The domain of many a Hollywood movie and popular fiction novel, the Wild West becomes home to Arthur Morgan, the leader of an 1899 gang in Red Dead Redemption 2. As with GTA5, there is an online game, Red Dead Online, but surviving the lawless frontier in the single-player campaigns includes trading with other in-game characters, fishing, and hunting.

The addition of co-op could further immerse you within nineteenth-century America and heighten all the thrills, dangerous situations, and nostalgic settings of Arthur's journey in a changing world. If nothing else, maybe your history teacher will give you and your friends some extra credit points for playing together.

8 Assassin's Creed Origins

Ancient Egypt's wonders are on full display in this edition of Assassin's Creed, and co-op capabilities would only allow players to dig deeper into its history. Like all the main Assassin's Creed protagonists, Bayek encounters famous figures - Caesar and Cleopatra, anyone? - while reenacting (and, in some cases, re-imagining) well-known historical periods and events.

Although true for any entry in the franchise, Assassin's Creed Origins in particular would benefit from real-time teamwork and strategizing. After all, the Great Pyramids aren't going to explore themselves.

7 The Legend of Zelda: The Ocarina of Time

Link Receives the Fairy Ocarina as Princess Zelda and Impa Watch in The Legend of Zelda Ocarina of Time

Yes, this game far precedes the rise of open-world games as most players define them. But it's also the first dip of the proverbial toe into the pond of RPG and open-world environments that kids of the Nineties experienced. And what a world Hyrule is.

From the spires of Hyrule Castle to the depths of Lake Hylia, The Legend of Zelda: The Ocarina of Time weaves a rich tapestry of characters, places, and lore that create a complex in-game culture. What's missing? Co-op. Having the ability to fight baddies and solve puzzles with the assistance of friends could make an already outstanding game even better. Maybe someday Nintendo will grace players with an updated, multiplayer version.

6 The Outer Worlds

In the vein of other great open-world games, The Outer Worlds lets you explore different locations and customize your character in dozens of ways.

Set in the Halcyon star system, The Outer Worlds introduces a vividly imagined array of planets and aliens that let you play out your wildest space-faring dreams. Co-op capabilities could allow you to join other players on your starship and create Firefly-style crews of space outlaws.

5 Fallout: New Vegas

"It's a sin" to not wish for co-op in Fallout: New Vegas (if you get the reference, you've likely played the Pip Boy's radio more than a handful of times). Traveling the wastelands of the post-apocalyptic Mojave Desert is always more fun (and, let's face it, survivable) with friends.

Taking on those radioactive mutants and New Vegas gangsters with a group via co-op could expand the range of outcomes and make exploration a heck of a lot more streamlined. On the other hand, though, nobody said that living after the world ends is easy, so maybe co-op would inherently undermine the "everybody's out for themselves" ethos of this game.

4 The Sims 4

The Sims 4 isn't quite an open-world game. However, the varied and open neighborhoods plus the full control you can exercise over characters make it a close enough facsimile to open-world gameplay that it merits a spot on this list.

Although The Sims 4 community lets you download custom characters and buildings created by other players, an immersive co-op experience has yet to emerge within the Sims universe. How great would it be to marry, fight with, and hold magical duels with your friend's custom Sims? Yes, there are certain mods that can turn The Sims 4 into a type of co-op gameplay, but the feature isn't available as an out-of-the-box option and is inaccessible to console players.

3 The Witcher 3: Wild Hunt

Geralt of Rivia Faces Down A Bear In The Witcher Wild Hunt

In this third installment of the popular The Witcher series, you can play as Geralt of Rivia while hunting down monsters of all shapes and sizes. In search of his adopted daughter, Ciri, Geralt uses his immense array of weapons and mystical powers to make complex moral decisions, defeat creatures, and find clues about the mysterious Wild Hunt organization.

Adding co-op into this game, though, would let players join forces against some of the scarier and more difficult monsters. As the popular Netflix series proves, The Witcher lore brings with it a rich collection of characters. Making some of those personalities playable within a co-op setting would enrich the story of The Witcher 3: Wild Hunt even more and create further ties with the show's version.

2 The Elder Scrolls 5: Skyrim

Dragon Flies In Skies Above Ruins In Skyrim

Anybody who has played The Elder Scrolls 5: Skyrim before will likely agree that this game would be absolutely incredible with a co-op option. Gorgeously rendered and unbelievably detailed, Skyrim's world is filled with different races, fleshed-out cultures, and unique cities.

As fun as exploring ancient crypts and buying houses alone is, just imagine the stories your characters could act out with co-op added in. Skyrim is one of those games that truly transports you into the life of your protagonist; teaming up with your friends' avatars would only strengthen the emotional bond between yourself and your virtual, dragon-slaying Doppelganger.

1 The Legend of Zelda: Breath of the Wild

Sorry (not sorry), but there's another Legend of Zelda entry on this list. Breath of the Wild is a given when it comes to wishing for a co-op update, though. The sprawling map of Hyrule - with its different climates, Ganon-destroyed cities, and wild herds of roaming horses - is a must-play contribution to Link's long and illustrious list of adventuring.

Scaling mountains and foraging for ingredients is not for the faint of heart, which is why Link should, finally, have some pals to help him out. The amount of new characters introduced in Breath of the Wild could lend itself to some awesome team-ups between Link, Princess Zelda, and crew. Nintendo, consider this a major co-op plug for the upcoming The Legend of Zelda: Tears of the Kingdom release.
