To answer some of these questions and concerns:
You
can create a game if you want. The reason I said just a scene (like a demo), is because creating a full blown 3D game would require alot more work. We won''t turn down or disqualify games. In fact, much of this contest is left open for the contestant to imagine and implement some original work, hence the vague rules and descriptions. I won''t try to give ideas, but just know that the only real limitations are that it must be 3D, it must have some sort of interaction (minimally moving around), and that it must have the four elements. Apart from that (and those API rules), you have free reign.
Also, you may use engines that you have previously created. I just don''t want to see something created using Genesis 3D, or the Blitz Engine, or Crystal Space, etc.
I am slowly but surely collecting the postmortems, and I will be archiving the old contests. I just can''t do everything at once.

Hope that helps.
