Console gaming in a home theater is really a blast, especially if the games support progressive scan or high definition resolutions and ProLogic II or Dolby Digital 5.1 surround sound. This website will give you the rundown on which games by console support 480p, 720p or 1080i resolution, 16:9 format, and 5.1 or PLII surround sound. As a Gamecube owner, I can say that Metroid Prime in 480p and PL II surround is amazing!
