Most games can be played with a controller, but recently I've been playing a few games that are like, controller only. These games are legitimately difficult to play with a keyboard/mouse.
>BallisticNG
Autistic podracing wipeout-port that is lightweight, clean, moddable, and can run on fucking anything. Big recommend.
>VVVVVV
We all know this. A classic. But it's been a while since I replayed it, and probably has been for you too. Worth revisiting, surprisingly moody atmosphere too.
>Rain World
Really, really cool 2D exploration game. Wilderness survival in an alien world, with cool environmental details, great area atmospheres, and weird wildlife. Hard as fuck
>N++
Remake of the old flash game. Focused platforming with crazy obstacles. Good for bite-sized 5-minute sessions
>Hollow Knight
Everybody knows this, no introduction necessary.
>Dark Souls
Same as above
>FIGHTAN GAMES
Been playing Guilty Gear and there's absolutely no fucking way I'd be able to manage that shit on a keyboard. Controller only game for sure.
>Emulators
Emulate everything. If you think you've played everything decent, you haven't. 80% of good games are locked away behind incompatibility, but emulators fix that. Go play good games, the best your computer can emulate.
