i can imagine a single player campaign would we way to much effort
leave that to the big game companies with all the resources for cutscenes, scriptwriting, voice overs etc
what i would love to see is some sort of multiplayer missionplay. some resources to fight about,
attack/defend, capture and hold. something like from Enemy Territory.
where other mech than just assault could be used to sucsessfuly finish the mission
FFA just for cash is rather boring in the long run. i know its based of the sucsesful counterstrike model
of earning cash and buying better equipment, but without some other goal it gets boring quick
