Interested, White Wolf RPGs are great, so any RPs inspired by them are always welcome in my book. That and I've been meaning to flex my superhero writing muscle to so I am hyped.

I'm really down to clown in any sort of context, I guess the only thing I don't really find compelling at all is the classic "teenage superhero academy/highschool" start (it just bores me on every level).

I'm a massive fan of using stats or some form of light table top rules to keep people on a similar power level. In reality, I don't think it usually matters nor do I particularly care how strong characters are, but by nature of the genre, superhero stories feel very dependent on good scale. My observation has generally been that it is harder to tell a nice story and have good RP flow if people are all over the scale in terms of power (e.g., it's pretty hard if your character is barely above a base human in power and my character can destroy the entire city without help).

My final thought is: please not a sandbox plot (lol).
