I currently own both a Dreamcast and a PS2. Aside from firing up my PS2 to run a few races on ATVOF, i'm usually hammering away on the PC or the Dreamcast. I for the life of me don't understand why the DC died... I think that it's far better than the PS2 will ever be. Oh well. As far as ATVOF goes.. I so far have beat the game with about 7 bikes and a total of about 12 times. Rainbow Studios did a helluva job on the title, imagine what MCM3 would have been like for the XBOX. Oh yeah.. check out the credits in ATVOF.. i'm in there :) (shameless plug - shutup Chris):p
In short.. if you have a PS2 and don't have ATV Offroad Fury.. you wasted your $300!
