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?
Yeah it’s a pain.
The ideal left hand control is something like a Switch controller, but larger, more like the size of a VR controller with more buttons available to fingers on the back/side. Basically half a game controller but with more buttons.
Keep the mouse for right hand. With that said I am not against the Switch motion controls replacing the mouse either, it’s extremely good when implemented properly at higher fps rates. Splatoon motion controls are as good as a mouse.
