This is actually similar to an Idea I had.
I wanted to bring Russians/Slavs(Both Soviet AND Democratic varieties,) Arabs, and South Pacificans(Not just Austrailians and New Zealanders, but Polynesians too.) Also a Nation consisting completely of Thinking Machines(And a single human base called Ambassador base. I wonder if one could script the robots to fly ships. Would need new voices too.)
I like what you are doing and will play the hell out of this when it's done. And, depsite the fact that I'm from New Jersey, if you ever use custom voices, keep the Irwinish idiots to a total complete minimum, but if you must, make'm pirates so I can kill'm. Those backwoods morons give aussies a bad rap. Most, if not the vast majority, are very civilized hard working people just trying to make their way through life.
