User-generated gaming is all the rage these days. PS3 has LittleBigPlanet and Unreal Tournament III; Xbox 360 has Xbox Live Community Games; Wii has Super Smash Bros. Brawl, Boom Blox, and now Blast Works.
This upcoming Wii-exclusive shooter from Majesco is based on Kenta Cho's Tumiki Fighters. With your mega-powered spaceship, you can blast away at polygonal enemies, and incorporate them into your ship, Katamari-style. Fifteen levels are promised to ship in the final retail game, and each promises to be a unique experience.
