Hi everyone, I've got some friends coming over at the weekend and we're looking for some 4-way Xbox action. We're interested in anything fun and action-packed. So far I've got GR:AW, PES6 and Gaunlet. I'm tempted to buy Doom and Small Arms (both 4-player on one machine, I assume?). Does anyone have any other recommendations? Are Doom and Small Arms worth getting for 4-player fun? Cheers!
