Yeah, I was thinking ColonyWars might be a little more obvious. I think I'd avoid the cw option. It gets to be too confusing when too many acronyms get used. Kinda like unix command shells. Too many 2 letter abreviations to remember.
Btw, is this based more on the Outpost series? Or specifically on OP2. If it's not specifically on OP2, then maybe don't use the Outpost2 channel prefix. From what I gather, this is sounding more turn based/Outpost 1 - ish. (But I may have to do a little more reading here).
