Nice, TC
The only thing that annoys me about the whole theme thing is the way you're stuck putting your character into a certain theme right from the start. Given that there will be a mechanical benefit to taking one you either box your character into a specific theme right off or you can't do it at all and on top of it you're being mechanically punished. I'd have really preferred if they had no net mechanical benefit, like say all the powers were swaps, and it was possible to pick up a theme during play. This is the nice thing about PPs and EDs, they can grow out of what the character actually DOES. I think it was a bit of an awkward way to implement it from a character development perspective.
