there needs to be an arcade list:
x-men
the simpsons game
alien vs predator
TMNT: turtles in time (also snes but even better for arcade)
smash tv
total carnage
saturn:
guardian heroes
dungeons and dragons (import only i believe)
dreamcast:
cannon spike
power stone 2 (co-op story and team battes)
nfl blitz: 2001
gauntlet legends
ps2:
gauntlet: dark legacy
the adventures of cookie and cream
---- i kinda feel that SMG galaxy should be taken off the list. it is really a one player game to the core with a haphazard two people mode.
