[@Veeks]I'm interested as well, but I feel the need to caution you about opening on a World Tournament. Speaking from experience, starting with a Tournament basically locks out any late comers from getting to do anything other than sit around watching the other players have all the fun. I've actually genuinely seen it happen in other games. Another aspect about Tournament arcs that isn't really fun to think about is that it will basically require all participates to be absolutely committed to posted, otherwise the game will grind to a painful halt whilst everyone waits for specific players to post. There's also the idea of waiting around for each paired up player to post back and forth until their fight is settled. Granted, this is a thing that will persist in ALL battles, but at least in non-Tournament settings the other players can still do other things while the fight is going on. At a Tournament... they're basically stuck in the audience unless they go out of their way to cause or find trouble (which can be a problem in and of itself).

I'm not necessarily voting against the idea of a Tournament arc altogether, but I am rather cautious about opening the whole RP on one.
