let me tell you this. i have always been a pc player, and even i bought xbox pad for games like platformers (currently Hollow Knight) or earlier Dark Souls games. now i know DS isn't games for me, i don't have the patience, agility in mind and fingers to do it all, but gamepad is useful in many more games. though FPS will only ever be played on k+m on my pc, that is clear :D

i'm saying there are games that can be played on k+m if you want to, my work buddy finished Dark Souls 3 on k+m while i struggled on pad, but that can be a painful and unrewarding experience. don't force it. go with a pad even on pc, some games are great and made for it.
