OK, I got two ideas.
1) The Year that Never Was.
Set in the year in Doctor Who, when the Master was in command of the entire world.
I imagine this would focus on resistance-style characters, trying to kill the Master, or topple his rule.
2) Un-named Gorillaz Rp
Something set in the world of Gorillaz, perhaps tying in with the story from Demon Days, or Plastic Beach. Ideally, this would feature more than just four people as Noodle, Murdoc, Russel and 2D.
Post if you think you'd like to join either, or could contribute to the overall ideas.
