Nearly a decade ago the 'sequel' to the Total Annihilation games came in the form of TA:K. This game was a wonderful experience and fun to play. I still have the CDs, just gotta get to installing it if I think of it...
The game, while not OVERLY successful in the gaming world, has a sort of cult following, I being one of these 'cultists'. If you're interested in what I'm talking about, check out this wiki entry:
