Everyone knows, to make an console port of an arcade game complete, what do you need? the joystick! It makes games like Street Fighter II and Mars Matrix that much more enjoyable in my opinion. WHich do you thing was the best console arcade stick you ever played on?
Mine are the Asciiware Fighter sicks for Sega Genesis and Super Nintendo

With the funcionality of an NES Advantage (without the sticky-ass buttons) with a heavy duty control stick, combos in fighting games actually work better than the actual arcade game itself, so If you want one for these systems, pick up one, better yet two. (I have two of them for my SNES and its wonderful)
