I honestly think that art should be one of the biggest if not THE biggest factor in the judging. Here is why:
When I was about, oh say 12, I used to go on Neopets. One of the biggest MMO sites, and it's similar in certain aspects to WiggiWorld. I would play these game and think wow, because the art was somehow simple yet good, it wasn't shaded completey or detailed massively, but it was genuinely very good art. Kids aren't looking for addictive games or amazingly detailed ones. They're looking for art thats simple yet good and easy to pick up gameplay.
Those are just my rantings and thoughts. And wow 43 entries, when I saw this I did not expect this much feedback.

If the search is any indication, there were at least 43 entries into the contest! I just put two new ones up on the front page - I still need to put together a collection page for all these! It's good to see the contest has been a success!
