I like the battle arena, it's a shame it doesn't get used much. I think it's always been a bit difficult to get people to join in challenges but hey, nothing to do but try. The thing is to find an all-inclusive theme that's more attractive than people's own ideas and well...that's a tricky one. The toy challenge did well because it got posted a lot of other places plus the front page plus newsletters.

There's an old thread on here somewhere I think it was Kurts, with mini 2D and sketch challenges which was also a cool idea. It's just something different. Personally I think mini-challenges should be super easy and cover modeling only, like a hairbrush, hammer etc. in order for them to work. If you wanted to post them in the main challenge area I could stick the thread and post small announcements as well because it would be really nice to see people join in.

Cheers,
