Wait! :) There's no other option. On large maps, the computer always takes a long time to make its move; you just have to accept that. You're talking about 3 computer-controlled opponents, but waiting for 7 is just awful. 3 is still tolerable. It's possible that there's another reason for your computer's sluggishness. I'd like you to specify what processor you have. Although, I don't think that's the cause; significant slowdowns only occur on very weak processors. Heroes doesn't require top-of-the-line models.
