Gaming

I have been a PC gamer for the majority of my life. But before that, i was a console player on the NES. But NES mainly had platformers, and no 3d games. So i am not used to movement and camera controls simultaneously at all.

I have purchased a Steam Deck OLED and it's phenomenal at playing platformers and twin stick top down games. However, i am absolutely sucking at FPS games on it. Can't make shots on the controller which are like muscle memory on my PC. I'm also having a slightly hard time on 3rd person over the shoulder games (not as bad as FPS though). It's probably because of my age (30+) I guess.

My question is that is there a way to improve other than 'git gud'? Example, is there an easy FPS game where I don't have to move or shoot too fast? Or a sample controller exercise game, like we have AimLabs for mouse movement.

Thanks.
