I used to be a console gamer. Bo2 on the Xbox 360 was my favorite game of all time. I moved to csgo, once I got a pc.
My gripe with fps games on the deck is it doesn’t feel like a console fps, it feels like a pc game. I obviously understand why but I wish I could think of a way to change that. The controls just feel awful to me
COD doesn't work on Linux, unfortunately. So no steam deck support either. Same with Destiny 2, which has imo is best feeling gunplay in any game I have ever played.
