ts is gonna sound like a paid promotion, BUT I gotta say, the Genesis/M30 controller from 8bitdo is probably the best controller I ever bought.
it works so well with RPGs. it's got an 8-direction dpad, 6 buttons on the right instead of the 4 on usual controllers, AND it's comfortable to hold.
it does suck that there's no official software to re-bind the buttons, but the default binds aren't that bad. also I love the feature where you can make the dpad behave like either joystick with a button combination.
so far, I mostly played Deltarune, some classic Sonic games, Eastward and Celeste with this controller, and it works flawlessly!
