I just joined a really fun SG on Infinity that is based on a Planet of the Apes concept. It requires that you create a new hero with strict costume guidelines, but if you like attention and deviating from the norm, it's worth it.
If anyone is game, contact me (Simian Galileo) or Simian Jones or Simian Smith on Infinity. I would imagine I'm the only Atlantan, but everyone has been really nice and funny in the recruitment process.
