To be honest, I'm always looking for one to play but have failed, completely, whenever I've tried to run one.
That is the thing with games, it seems backwards on Pbp
First you find good players, who know the system, are aligned somewhat on genre, then the game idea is put forward by the GM, then he builds it for those players.
True, we have the Game Proposals thread, but it would appear, a very small pool of HEROphiles.
My personal cage match with HERO is Exp earn rate and spending justification.
My personal tastes run to running games in the Fantasy or Star Hero.
As subset, Post Apoc.
I like Opera in my games, not saying epic points, but where Characters are central and are motivated to be something other than the owner of a bar or the best Miller of grain or most competent Mayor of a city, unless of course that is the Empire's Capital.
