i'm not that big on online mp *because* of halo, lol. i'm really looking forward to gta4's team based mp with a dynamic environment. i think every match will consist of multiple instances of "HOLY SHIT did that just happen?! HAHAHAHAHA!!!" and stuff like:

sniping the tires of getaway cars while sitting on the skid of a helicopter hundreds of feet in the air

cleverly set roadblocks and traps with multiple players popping out from behind corners to rip apart an opposing team's car with shotgun blasts

bike chases with real players; dodging grenades dropped by the player you're chasing

using the dynamic environment to your advantage i.e. funneling an opposing team into a traffic jam and letting loose the grenades and rockets

etc.

i think once ppl see exactly how dynamic the single player is their heads will explode when they realize that they will have the same experience in mp
