Prince, when you get the chance, could you explain why you're favoring just one character per player rather than two?  I feel like you must have said already, but either I forgot or I missed it.  In my eyes, having two characters opens up more options for each player to take if they so desire, while they need not do two if they'd rather do just one.  It could be more fun, further interaction with other players' characters, and possibly give a player an option to play with themselves if they feel like it would be beneficial.

I say this because in a previous multiversal RP I was in, the hero characters started in one place and the villains in another, not permanently divided but guaranteed some time with people in their own way of thinking.  Being able to have two characters made it possible for people to have one in each camp and explore each side of the coin.  Of course, I have no idea what you're planning with the RP, so this may not be at all necessary, but I thought I'd bring it up.  If you're on the fence about this topic and are thinking of putting it to a vote, mine is certainly cast for a two-character cap.
