• OlliOlli
• Apotheon
• Castle Crashers

Games like Rocket League, Battleblock Theater and Coffin Dodgers.

• Gauntlet
• Lara Croft series (not Tomb Raider)
• Bastion
• Trine series

Magicka if you're playing local co-op.

Metal Gear Rising (but I see that you already fisished it), Jamestown, any platformer such as Super Meat Boy, LUFTRAUSERS, PAC-MAN Championship Edition DX+. I can't think of any other game, these are the only ones I've played with a controller.

Lethal League, Final Exam , Double Dragon Neon, Dragon ball Xenoverse, Mortal Kombat IX and X .
My current fav's on controller.

Castlevania Lords of shadows(both), Darksiders (both), Witcher 3(suppose W2 will do as well).So, yeah, most of RPGs;)

Almost any sport/fighting/racing game. But, if you want a name for a much harder with a keyboard game, I say Super Meat Boy.

The witcher 3 ane dragon age inquisition

The first thing that comes to mind is "Brothers - A Tale of Two Sons", a game that uses the controller in a very unique and interesting way. Though this game is playable with keyboard/mouse, a lot of what makes it so great is lost (which is why the Steam page says controller required).

I was in the same position last year and I enjoyed these the most

Tomb Raider
Skyrim & Fallout 3 & NV
Dirt 2 & 3 / GRID series
GTA 4 & 5 / Saints Row 3 & 4
Witcher series

Basically im using xbox controller for arcade racers, and every other game where i can trade a little accuracy for "cinematic smoothness". The visuals feel much more immersive when you don´t continously flick around in split seconds. Variable walking pace on left stick totally sweetens the deal.

Freedom fall :-)

Castle Crashers
GTA 4 (mostly due to it being the worst port ever)
Shank II

Every arcade racer needs a controller for me, if it doesn't support it then I just use Xpadder. The only game that was horrible with a controller was Dirt 1, the game had a dead zone (that you couldn't change), along with my controllers dead zone made it to where if you move the joystick even a little bit then the whole entire car spins completely out of control.

Every devil may cry games with a controller.(I beat 3 with a keyboard/mouse but 4 is hell without controller, because keyboard had some problems with forward input + another input).

For 3, you need to do a little bit of tinkering but there a nice guide on steam.

Grid 1 and 2 is better with a controller, like any racing games.

Killer is dead is fun with a controller but you can play that game very well with kb/m(suprising me)

I use Pinnacle Profiler so I pretty much play every game in my steam library with a 360 controller, it also works with the xbone controller, and it has a free trial version. Anything third person works great - Assassins Creed Series, Sniper Elite, XCOM, Tomb Raider and Hand of Fate. Platformers are great with a controller, Mark of the Ninja, Super House of Dead Ninjas, Super Meat Boy. Arcade games also work really well, Pac-man DX and shmups like Crimzon Clover and Jamestown.

Phantom Breaker :>

Stick with Dark Souls.

I got my xbox controller only for dark souls tooXD But i used it then in many games.
I dont know which games you like so i will just place some examples:)

• Dragon Age Inquisition
• Oceanhorn: Monster of Uncharted Seas
• Secrets of Grindea
• Brothers - Tale of Two Sons
• Witcher 3
• probably many Platformers
• I dont know if you need more examples and i think its possible to search in steam for controller support games too maybe?;)

Ori and the Blind Forest, Raiden, Jamestown, Cave Story, basically most 2D action games (be it platformers, shmups, brawlers and so on) that don't use the mouse for aiming. For most games that uses a free camera, or where having good control of the camera is helpful, it's better to stick with a mouse & keyboard, as long as the controls don't have some form of quirk that makes use of the gamepad (Metal gear Rising & Dark Souls are good examples of games where a controller is near mandatory, while games like The Witcher 3 or GTA 5 are games that I found the lack of good camera controls to be too much of a detriment to make a gamepad worth using).

Every platformer, beat'em up and hack'n'slash game.

Castle Crashers
Battleblock Theater
SpeedRunners
Foul Play

Devil May Cry series, Castlevania Lords of Shadow - the one reason I got my controller, I suppose you could play any Assassin's Creed game on it... I also played XCOM Evemy Unknown, Shadow of Mordor, any racing game, Metal Gear Rising which is quite fun, any generic fighting game e.g. Mortal Kombat, Street Fighter... Some of the oldies like Prince of Persia, amazing games, loved them all, even the last 2... Batman series perhaps... oh boy, that's a lot of games.

Why was MGS5 unplayable? maybe giving the reasons will help us give you better recomendations.
Sleeping Dogs, Tomb Raider (2013), Dust: An Elysian Tail, Rocket League, Batman Arkham series

Deadly premonition, that game works amazing with a controller !

if you dont mind camera endlessly spinning around you, thats it.

skullgirls, castle crashers? :D
