So, I bought the Snes controller (new one, with R1,L1) so that I can play 4 games which I liked, but found too challenging with a keyboard : Teslagrad, Odaluss: Dark Call, Volgar and AM2R.
@koima57 : I'm not looking for Snes games, that would be easy to track down, but rather new games which don't require more than 6 buttons. Example, Sundered works good till you unlock new abilities, at which case you can't play anymore. Skullgirls works awesome, but I'm missing a button or two, Apotheon requires an analog stick. etc.
@dtgreene : I meant out of the box ready to play, I might decide to try out third party software later, but for now I want something simpler.
@Mr.Mumbles :
So that's a good singleplayer list.
I'll try Spelunky next, I didn't think of that.
So what I'm looking for now are nice fighting games for 2pl , because of some reason none of the SNK games work for me, and Skullgirls is fun, but I would like more.
