[Jeff The Ninja]

You have all played these games, games that were awesome in arcades but no company had the right mind to port them.

WWF Superstars
WWF Wrestlefest
Blood Storm
Black Tiger/Black Dragon
Ninja Baseball Batman
Spider Man: The Videogame
Vasara 1+2
X-Men
Simpsons Arcade (ok, so it was ported to DOS and amiga, but it was done so very poorly so it doesnt count)
Vigilante (an update to Kung Fu master)
Sonic The Fighters

(Edit)

I just found this game while looking for roms. It kicks supreme ass and you never even heard of it.

Avengers in Galactic Storm
