I could see where it'd get really addictive because it would be like a "Comp-stomp" kind of game, but asking the player to get creative on defeating the AI. Tossing out another idea, if you didn't want AI at all, maybe you could also have it where one or two people are given large pre-built factions, but they have to face a larger number of human opponents. This may not be as feasible, though; people have brought up the balancing issues with other topics, and I think that may well apply here too. But, I'm glad to see a few people might like it! Anyone have any other ideas on how to deploy an "instant join" atmosphere to the game? Of course, keeping in mind that there is a large "resource" of time in developing an army.
