Ive thought about this for a long time, and Ive taken the step in the Official side of AC, and Im sharing so maybe you guys can get some ideas on about how to do the gema olympics.

With Hp we have (lol, he has) done a high jump map, but maybe we should consider using actual "famous" maps for the olympics, or build our own. It can be a very fun thing to do together, so Im listening to your ideas!
