This is a pretty great idea!
Just wondering, could there be any planned opportunities for this to integrate with clan wars other than the standard multiplayer ones set up through the Toriclan system? Many clans ([T] included) don't have that much of a multiplayer presence and would be more interested in having alternative clan wars such as clan replay wars.
If not, fair enough, I'd imagine it would be a bit trickier to run. Just throwing it out there anyway.
