AI is usually the weakest part of an RTS. In fact, it’s so assumed that real-time strategy games will have bad AI that it has caused us some grief in our reviews because some reviewers (you know who you are) barely bothered with the sandbox game, focusing instead on the scripted (and relatively bare bones) campaign. It didn’t occur to them that the single player sandbox was the meat of the game.
In Ashes, the AI operates on multiple CPU cores at once (a minimum of 4) and does so asynchronously from the rest of the game simulation. This is important because you can watch, in real-time, the AI adapt and counter your strategies. It also matters because as we get better at the game ourselves (or ahem, watch others) we can keep making the AI better and better.
