Wind is modeled in the game with a speed and direction - you can see this with the blades turning in your wind machine. It's far more than an energy source. By this he meant that like the king if you lose your commander it's game over, but at the same time he is very powerful, like the chess queen. He will heal, for a cost, with time if damaged, but with both sides given this Achilles heel it seems Total Annihilation games will never be won for sure until the very last blow is struck. Indeed that game has one - the Core have learnt to transfer minds into machines for immortality, the Arm reject this, hence a long and bitter struggle over four millennia.
Commanders are they key to battles, being able to be teleported between planets.
Total Annihilation has 25 campaign battles on each side, though there won't be a map editor available until the add-on pack comes out. That doesn't detract from network play where up to 10 players can compete in LAN games. Cavedog are too small to set up their own servers yet according to Jacob. The minimum spec is a 16Mb P100, but a 24Mb P133 is what Jacob thinks will be recommended. The game can be run, or at least has been run, at screen resolutions up to 1280 wide, but that likely requires a stonking P2 processor.
