I believe around April Fools 2012 Esp1222 hosted a Hunger Games that was much like this. I would gladly host or help host something like this with Noobscraft when V6 comes out. Since I'm guessing there will be 2 or 3 main Nations, hopefully 4 as to make the championship game more interesting, there could be qualifiers within the Towns, then a First Round within the Nation the Towns belong to. As a rule, all participating Nations must have NO LESS THAN 4 TOWNS within them. As another rule, towns would have to have AT LEAST 20 members in them to qualify. The tournament could be called "The Noobscraft Town Battle Tourney". Each town should 1 or 2 arenas in them, unique from other towns and both would have to be different "themes". Like woods, mountains, deserts (maybe not a good idea too flat), a volcano (naturally spawning of course, or the admins could help with the building of it), an underground cave system, a secret laboratory, a giant mansion, etc. As a twist, if the winner of the First Round's (within a Nation) partner was killed in the games, the dead person is brought back to make there be 2 people per Nation. The losing towns would have to pay the victors' town 5k Noobz each. Then the Town Mayor would give the victors of his town a minimum of 1k each. There could also be a second place game to have 2 more players from a DIFFERENT Town Within the Nation go on to the Final Round. Then we would go into the Final Round, between Nation Champions. The winners of the Final Round have the other Nations pay the victors' nation 20k each (the tax split among each of the town OR have the Nation Capital pay it all off themselves (AKA the person who created the Nation's town)). Then the winning town could have a big party or something and they'd announce the location of the next Noobscraft Battle Tourney town location for their Nation and then pick the Final Round's location. To make things from being a huge blowout, the winning town from each Nation of that month would not take place in the next month's tournament.
So, my conclusion is that this looks like a great idea. We could start an official "Noobscraft Battle Tourney" thread after V6 is about a month or two old and then get towns started with the building of the arenas and selecting their fighters.
