Here's the idea:
Every clan has a planet. The planet is made from 9 levels - 2 CTF, 5 Battle and 2 TH. The levels are made from tilesets with same mask. The tilesets and the levels are made from the clan. Every clan can attack other clans' planets. Attacking them means that the attacking clan has invited the attacked clan to defend their planet. If the attacked clan doesn't respond (or start server) for 1 month, the battles are won by the attacking clan, so the planet is also won by them. If no, the clan who win in more levels wins the planet (if this is the attacked clan, he just defends his planet). When the attacking clan wins the planet, defend clan must send their files (the tilesets and the levels) to the winners and they can make their new planet. There's no clan that can have more than 1 planet made by them. If a clan won a planet, he can modify the levels, but he can't modify the tilesets. When a clan is making his own planet, they must made their levels in that way, so attacking clans can also win (even if it's hard). No seekers allowed in the levels.
I think that this will make Jazz JAckrabbit 2 more strategic. Nice playing!

Uh, so you want a clan tournament with lots of "planets" that belong to a clan and you "attack" things to make them yours? whats the point of owning anything, why are all the masks of the tilesets the same, whats the point in even playing if you can make the levels not for balance, but for your advantage? How about I just make a ctf level where all the other team is stuck in a box? Why no seekers? what in the world is this? How in the world is this strategic?

Voala!

My idea of hard is a level that you get stuck in a box and can't do anything without cheating.

I like the idea though (well, I can hardly play JJ2 anymore, but whatever); but the main problem is, you should have some "neutral" people design the planets, and it may be pretty hard to find someone willing to do lots of 9-level packs.

I think the idea would be good if there weren't some... "restrictions".

..mostly that we have like, what, 2 active clans?

Nay Faw, you're thinking of level groups.
We have about twice that many clans still active

Well, there can be some sort of Neutral clan that checks the new levels...
