Scott Pilgrim vs. The World: a movie, based on a comic book, that features Michael Cera doing martial arts.
Scott Pilgrim vs. The World: an old styled side scrolling beat 'em up which looks to be two player, with awesome pixel graphics, a sick chiptune soundtrack, and an underlying story of chivalry and love.
When I first heard about the game, I immediately wrote it off. How good could a game with tie ins to a Michael Cera movie be? Then I saw the E3 trailer.
This thing looks good, folks. It's not the most cutting edge in terms of graphics and technology, but it doesn't need to be. In the vein of Castle Crashers, good beat 'em up gameplay, retro styled graphics, and a slamming soundtrack will get you places. And yes, being an XBLA/PSN title, it will cost under $10. UPDATE: Yes, Scott Pilgrim vs. The World has 4-player co-op. Can it get any better?
I'm sold, and you should be too.
