So far there's been no contests featuring the adventure editor. I'm guessing that's at least partly because a quality adventure takes a massive amount of time to write and create, limiting the quality and number of entries, as well as not being able to judge an adventure by simply looking at photos. However, a contest challenging users to create a single static scene in the adventure editor according to a theme would take much less time meaning more people could enter, and could be judged based on their photos like any other contest. User submissions would be photos taken of their scene and a sporepedia link.

I like the idea, but yeah like you said the issue is being able to share adventures and judge them. It would certainly get me more interested in making an adventure if I knew all I had to do was make a single scene
