I found that to design games for the crowd seperatly and merge them, works wonders. One crowd gets a hyper-challenging rts, the others get to play heroe units making all the difference in a small dota game, playing off the the hyper-rts. The OPs can take over and micro, but they wont never micro as well as a human, for whom it is the whole game.

One example.. of course, you goto keep it civil. No pro players dunking on the mom&pop gamers who just want to have 5mins of fun on a tablet.
