At first I thought it was great on the PS3, then things started to creep in like being sniped on spawn areas, this is more of a map design fault than anything else, if you give people a chance to camp and snipe they will, nothing is more saddening than spawning and having a tank and gunner shelling you to Timbuktu as you spawn, there's no point in playing.
This is a problem most first person shooters need to address. BFBC2 had nice crisp gfx but it was the MAG beta for me at that time which got played the most.
BTW I think this will sell loads.
