Well.....until a week ago, it was the XBOX. I have been playing such classics like Metroid Prime, Mario Sunshine, Jet Grind Radio, Animal Crossing, and Daytona USA from my Dreamcast and GameCube systems. The PS2 has even been collecting dust too, but my usual Grand Theft Auto VC sessions saves the system alone from the same fate as the XBOX.
So, what happened to the XBOX? I sold it to a friend. It just wasnt the system for me afterall. However, I still have a PS2, GameCube, and also a Sega Dreamcast all hooked up to the same TV.
