Make a game which is a universe.
Make the game good.
Starts on January 11th, finishes on February 11th.
The game needn't be a universe, the game needn't be a game, and a universe needn't be a universe. It might be a closed system, a self-contained collection of concepts, a microcosm, anything.
If you haven't made games before, and aren't sure where to start on the technical side of things, just ask : there're plenty of people here who can give guidance.
When you do decide to post about your game, say it's called "Cats Under Fire", post a thread about it with the title "Universe Pageant - Cats Under Fire". When you've finished it, edit the first post to give it a new title - something like "Universe Pageant - Cats Under Fire [ DONE ]".
Any questions, please just ask below : )
