I am behind the XBOX, which is strange for a Macintosh User!
It is just the most powerful system and has the best online support with it's excellent XBOX Live system. In fact I like it so much that I sold my PS2 because I just didn't care to play the games with worse graphics, especially since I like Racing and First Person Shooters. Some people like the PS2 because of RPG's but I am an old school paper based RPG fan, so I have never like computer or console RPG's.
I sold my Dreamcast as well, but I will never get rid of my Sega Saturn because of SATURN BOMBERMAN, which in my opinion is the best multi-player game of all time, and has yet to be topped. And all the 3D bomberman titles have been awful!
