Idea is very good, but we need to register 32 guilds with at least 3 members, so the games could be kinda equal. For the event we need to have a set of rules, we have to establish a date and an hour for the games to take place, we don't have to allow players to migrate from a guild to another between the games etc.
As I said, is a good idea, but will be a bit difficult to organize all this so everything could be at least perfect.
