Good idea Mauro but way too ambitious. With KOTH and the Rating Bash going on (+ a few fun games) there is no way I would have had the time to join
Also, the winner of any 5 - 20 player games is almost down to pure luck. Sure, the winner will be a good player, but with such high stakes everybody would gang up on the favourites at the start. The only true test of playing skills comes from one-on-one games (or games with pre-set teams).
Give the Rating System another half year, and you will find most of the contenders for the "Greatest players of the galaxy" on the top (Stone is still AWOL though).
