This is just to clear everything up.
Tools:
I'm just going to allow SC and GM, for the reason that, A) we all have around the same limits, and B) we all know how to use it.
Graphics:
Graphics must be original, that being said, I have no problem if you base your sprites and such off others, (like my avatar). You must of course have the original creators permission.
Theme: There is none.
Engine: As there's no reason to make your own gridcode and such when its out there, you may use other's engines, just add it in the credits or splash screen if using GM.
Development
You may work on your engines now, but no "game" work(graphics, music, etc.) should be started until the 20th (as to provide everyone with an equal chance). I would use makeshift sprites until the 20th.
Games are due January 20th. Voting begins next day.
Comments and suggestions are welcome.
