Ok, so we all know that Mario Party is the best party game out there, but I (gasp!) don't have any nintendo consoles... I'm looking for an xbox game that can be played for hours on end, ideally by 4 people at a time. I have Mashed: Fully Loaded, which is my current favourite, and I know Burnout 3 is good fun for two, but I need more ideas. Anyone spent hours with a bunch of mates on one game?
