Best Live Arcade Game?

Puzzle Quest is really fun, and it lasts ages for a xbla game. Try the demo first, as it is exactly like the full game.

Assault Heroes and Heavy Weapon are both good arcadey/shooter fun

my favs are:

Doom: played it when I was 10 and I still luv it now (only 400 pts now)

Commanders AOTG: i am a sucker for a turn based stragety game

Others: SOnic 2, TMNT, Castlevania

Wait for the new HD street fight! that will be the bomb!cruxe

ya wait 4 the trust me
