Sony, and, most recently, with much rejoicing, finally(again) Nintendo, have rights to Squaresoft games...and IMHO, whoever runs Square software runs the game market...although Microsoft did recently aquire Rare and bought Bungie (Halo) when the system was still in beta, and Nintendo has Retro Studios (Metroid Prime)...still go with the proven winner...PS2 and a GameCube as a second system. The XBox will soon be a desktop computer system, but you already have one of those.
