For example most fighting games and arcade beat 'em ups I go leverless with my keyboard. For 2D platformers I like to use a d-pad. Then for 3D games I usually go to my 360 knock off controller.
I recently started playing old tank control style games in the vein of Resident Evil with my keyboard and it works surprisingly well. Old Tomb Raider also plays well with the kb set up.
Anyone else?
For fighting games I use the leverless I 3D printed. It uses a Raspberry Pi Pico board inside because there’s an open source firmware that is great, it’s called RP2040-CE.
For shooters like Risk of Rain 2 and Ultrakill I use keyboard and mouse, tho I really want to learn gyro + flickstick on controller since those who use it swears that it is as good as kb + mouse.
For everything else I usually use controller. I used to use a DS4, then I used a Dualsense and now I use a Flydigi Vader 3 Pro. Chinese controllers are where it is at.
