I really enjoy StarCraft 2, and mostly want to play with my friends. We enjoy playing Co-op vs. AI (with 3 or 4 of us humans on a team). But I would like to get into some skirmishes against them as well.
Unfortunately, I happen to be much better at the game than many of these friends. The one time so far I have convinced a friend to try a 1-on-1, it wasn't really a competition even with me at 50% handicap. That sort of thing makes them not want to play with me anymore, which is the last thing I want to have happen.
What sorts of handicaps (other than the ones in the matchup screen) are appropriate to tune the difficulty for us such that matches between my friends and I will not be obviously 1-sided? In particular, I don't want to have to pull punches and play poorly on purpose; I would like for it to be challenging on both sides, and for all involved be able to play to the best of our abilities.
(Classes of handicaps I have considered, but not yet tried, would be arbitrary limitations on things I am not allowed to do in the game such as build certain units or something.)
