It depends. What genres do you like?
If you like 3rd person melee, definitely get No More Heroes. I think it's the best game in the genre, thanks to really fun controls. It's also hilarious the whole way through and has more personality than most new games.
If you like 2-D run and guns, get Metal Slug Anthology. If it wasn't for the Orange Box, this would be the best deal in gaming.
If you like 4-player 2-D fighting with platforming elements, items, and stage editing, get Brawl.
If you like 3-D platforming, get Galaxy. It's the best.
And I always highly recommend Elebits, because it's a cross between Katamari and Ghostbusters. Elebits and Metal Slug Anthology were launch titles and should be super cheap by now.
