I like to use a mouse in most games, especially first person, point and click, and anything where I can control the camera. I use a controller in side scrolling platformers or other 2D games.

I am currently playing No Man's Sky with mouse and Cuphead (not easy at all) with a controller.

Edit: Here are some of my favorite games that I played with a controller:
Brothers: A Tale Of Two Sons - You control 2 characters at the same time. On a controller, each character is controlled with an analog stick to move and a shoulder button to interact. The game itself is not difficult, but it will take some time to get used to the controls.
Fez
Dust: An Elysian Tail
South Park: The Stick Of Truth - Don't remember if I played this with a controller, but it should be very easy to play with a controller and I enjoyed the game a lot.

filter by controller support, sort by user rating, just play

i play most console ports with a controller
maybe start with side scrolling games like Guns, Gore & Cannoli, Guacamelee!. classic console games
then, fighting and racing games if you like them
its great when you want to lay back an relax

I am team Keyboard and Mouse. I ordered the Steam Deck. I'm looking forward to it. Looks like it will be very customizable. I like that. Will I like it better? Will I use both? Will I go back? I have no idea. But I'm looking forward to finding out.

I don't have any recommendations but I will be checking back to see what everyone thinks are good game to play with one.

Generally, platformers/metroidvania type of games are good to get used to pad.
Personally, I would recommend either Ori and the Will of the Wisps or Blasphemous..

any of the mega man games are great with controller

I'm horrible at controller gaming. But this little platformer is easy to get into.. Castle of Illusion.
Well, any platformer I guess. But I remember liking that one for it's simplicity when I was getting used to the ps4 controller.

If you wanna get good at games that support controller, I recommend playing some third person games. Things like the Squeenix games: Hitman, Deus Ex, Tomb Raider. Enslaved. Or if you have a chance to own/play, Horizon Zero Dawn. I play most of my games with a controller, with the exception of some first-person games.

I played Dead Cells and Guacamele using the controller. They play out smooth and much better than keyboard and mouse.

2D games are what I'd start with. I didn't use a controller until 2 years ago and the first games I tried it on are the 2D ones (Hollow Knight, Dead Cells, Rogue Legacy etc) and love it with those vs kb+m.

Although I still prefer kb+m for 3D games. I still have not gotten used to turning camera with analog stick. Feels clunky.

i think that any game that is possible to play slow (sort of fallout4,astroneer,deus ex,prey etc.) is good for learn play with controller ,

vice versa fast games (runners like sonicc or fastpaced tc.) or games with quicktimes\timing attack\defend or that require to holds buttons or push buttons repetitively fast is not
(and they also damage the solder parts of thumbstick controllers or buttons very fast too that sadly in most of controllers it's not interchangeable )

Personally, I haven't really played consistently with a controller since the good ol' N64 days and pretty much sucked with using them since. Although I do have the Steam controller, which I will pull out occasionally when I want to stream my PC to the TV, I will only use it with games that don't require a boatload of button presses and easy to map like racing/kart games (incl. Audiosurf 1 and 2, and Riff Racer), TemTem, Diablo 1-3, Telltale games and VN's, or sitting VR games with gamepad support. Console ports like Crash Bandicoot, Sonic, and other classic style 3D platformers and old school sidescrollers can also be easier to play with a controller.

I recommend you to play Guacamelle. Very interesting game, especially in coop

I took a look at your gamepage.

Games I played (and liked) with controller:
Evoland
Figment
Moonlighter
Wildfire

Other suggestions:
Terraria
Tomb Raider games
Children of Morta
Forager
Ghost of a Tale
Minoria
Smoke and Sacrifice

I personally use a nintendo pro controller with my pc and love using it. Sometimes it's easier to use a controller (like when movement is only for a qwerty keyboard and not adjustable to azerty) But sometimes it's easier to use keyboard and mouse.

It depends on how much of the keys you can adjust.

Have fun!

+1 to any platformer / Metroidvania recommendations (trying to remember the name of Klei's ninja stealth game).

Fighting games, for being able to slide across the D-Pad, but that will take practice.

A good arcade driving game for getting to experience controlling a car without being full-gas/full-brake/hard jerky turning all the time. (A dedicated wheel is always a better option, but for arcade drivers instead of sims, it shouldn't matter.)

A good 3D platformer/adventure with auto/locking aim would also be good. Something like Prince of Persia, Assassin's Creed, or maybe even the new Tomb Raider games (though m/kb is probably better in the last one).

...

I also used to be a die-hard kb/mouse person. CS1.6, TFC, TF2 days. And for a good shooter game, the mouse is still always better, imho. But I've opened up. Controllers are good, too. Sometimes better, even. Use whichever input option makes sense for whatever game you're playing.

I feel like controllers are best suited towards fighting games and racing games. I also think that the Nier series works better with controller, and I love both of the games!

A Doom Eternal dev said he prefers to play the game with a controller, maybe Doom isn't bad either. (I personally would never play a shooter with controller but who knows.)

As you said you might buy South park: The stick of truth I would recommend that one. Pretty simple to play with controller.

A short hike and Alba: A Wildlife Adventure is also pretty relaxing games to play wth controller.

Edit: Would also recommend Cat Quest 1 and 2.

Hades. It is a good game overall and plays nice on a controller.

For me personally I prefer KBM and use controller only if the game 'feels' better with it.
I enjoyed playing Yooka-Laylee and the Impossible Lair on controller. MGRR as well. And other games too. So pretty much platformers and slashers for me.

Looking at your library, Dragon Age II and Inquisition are probably better on gamepad and easy to learn and you have plenty of playtime in them. For things with less time, Borderlands might be good and Tomb Raider also. Enslaved: Odyssey to the West was great when I played it on an Xbox 360 so you should have no problems there and it's one of my favorite games ever, I think you'll love it.

Maybe Thief and Little Nightmares but I have less experience with those.

And yes, buy South Park first then Horizon Zero Dawn and Tomb Raider last when it comes to difficulty learning a gamepad. All are recommended.

One finger Death punch.
Rampage Knights
Neon Abyss
Everhood
Cuphead
South Park

I prefer KBM as well especially shooters but some games are just perfect for controller as well

I bought my first controller a month ago (xbox series controller) and for me the biggest plus is, overall it is more relaxed to play.

When I sit on computer, with kb+m I always feel little more competitive, and overall less relax. With controller, I feel like I really play for fun, thats all.

btw, I think Metal Gear Rising: Revengeance can be a good option. It was the first game I played and I had fun.
