My favoritest games, from my youth to the present:
Star Wars (even though, as a little kid, it was a bitch to reach the controls on the stand-up version)
Sinistar (great voice!)
Street Fighter II
Aliens versus Predator (an arcade game with a decent plot!!!)
Crazy Taxi
Ocean Diver ( a recent shooting game from Sega–you go underwater and shoot mythical creatures with a huge pneumatic gun. Loads of fun, but $1/credit eats into the bank account too fast)
