Oh my god. I am absolutely loving this game, epic is not a big enough word to describe it. There's something about it which just harkens back to the no-nonsense pure gameplay days of the arcades. And what makes it better are the sneaky references to other games. Riding a mototcycle at incredible speed to the music of Afterburner was just awesome, and when I got to the Space Harrier clone level with Space Harrier music and even some of the original sound effects (topped off with the boss music from Fantasy Zone) I nearly wet myself with joy. The game just gives you such a rush, it's been a long time since I finished a level in a game with my heart actually pounding hard (while not being frustrated by dying a few times). This is the best thing Sega have released in years, and a damn good reason to get a 360 if you're still on the fence.
