This is the most recent release (well, almost) in the fantastic line of games that came from Total Annihilation, which also includes Supreme Commander. It's now on sale for about $1, which is a little annoying considering I paid $50 only a year ago!
I haven't yet had a chance to play it properly as my old PC wasn't up to scratch, but I'd be very interested in playing it with some folks if anyone wishes to buy it and play it with me. ^_^ The few hours I did try playing it, it seemed epic.
Anyway, here's the link!
