Yeah there's quite a bit of variety.. I've heard a lot of people say they love that one. I've always hated Xbox controllers though. I just downloaded this SNES emulator anyway, but it's pretty nice and I havent played with all the settings. I'm pretty good just using a keyboard anyway I'd wager. Just with this game you have to hold the run button while shooting to fire at 45 degree angle (side scroll style), and hit some bad guys. (It's Like the old Ninja Gaidens, but western shootem up)
Theres a lot of jumping on things, and dodging/sliding involved. Plus I was guessing all the keyboard controls even for the emulator options.. It doesn't bother me to learn new controller set ups or multiple setups for any game much though honeslty.. For some SNES titles I can see having atleast a USB SNES controller though. I'll wait 'till something actually pushes me to want one.
