ID softwear is making an online mmo pve game out of Quake. 5 classes with various abilities kind of like Planetside.
personally, i would have gone with Doom myself.
the game sounds very group dependant. planetside didnt do very well and it was pvp. i just cant picture a planetside pve game doing any better. especialy not one focused on groups. but ill give it a spinn. im a big fan of Quake, but if you have to repeatedly fire a chain gun into a monster for 3 or 4 minutes to saw away at its hitpoints..........lets just say ill treat it like a newspaper.
