"Sealion" based upon the WWII air battle of Britain, two teams of tori's compete against each other for points. Only, fighting should take place in the air, without touching the ground. Would be harder on things like xspar without DMs, but still able to be pulled off. Just an idea, of course.
We could ask worldeater or whatever his name is (he's in obey) to make mods for that. I think it would be a pretty original event, and original events can get gm sponsorship.
