Certainly a worthwhile game for a few bucks. It boils down to what resources do you capture first, how thinly can you spread your forces and still expand, and what choke points to fortify. The campaign is pretty brief but provides interesting puzzles. The achievements provide a bit of replay value as well. My main complaint is that I found the AI too easy in skirmish mode, meaning this game doesn't provide much challenge after you've beat the campaign. Either I'd like to be able to fight multiple teamed AI or make them individually more difficult, even if that's just by giving them extra supply cap or resources or something. There's nobody on multiplayer.
