For three years, Geometry Wars has been the star of XBLA, the poster child for download gaming, and a title responsible for grinding millions of thumbstick sockets down to a fine white powder. It was Retro Evolved that reminded us that games don't have to be bulky to be epic, nor do they need to be brutal to be sadistic. A reminder that games could be atom-sized chunks of pure digital malevolence, flinging sound and fury at the player for less than a minute at a time.
