Interesting indeed - but still far away from a proper agent based emergent AI that can play the whole ability range of the game competitively.
Also interesting because they mention that Starcrafts path-finding is so hilariously broken that they had to write their OWN pathing logic from scratch. Which imo is cheating. The AI does not play the same game humans play, so it always wins when there are no exploitable loopholes left.
In a sense, this is also the "brute force" approach
