I like the idea of star trek roguelike. If you had kirk, spock and redshirt, redshirt could die and it's no big deal, just beam down another one, but if spock or kirk die it's game over.
Anyway, where can I find the rules? Is there a requirement to make the game playable on any computer? Does it matter if you need to install a different program to get it to work on your system?
I would use Blender Game engine which can run from a stand alone .exe on windows or be run using blender if you don't have windows, or it can run in a web player but you have to install a plug-in.
In my case it would probably be like a 2 day roguelike as I doubt I could spare a whole 7 days of free time as I'm a dad to a two year old boy, however I've got lots of code laying around already that I can port, and some old static or two frame animation graphics I can use.
I think it would be possible to finish the game by the deadline (or at least get it playable).
I'm going to have a team of robots trying to escape from a secret underground governement research facility. You'll start at the bottom of the dungeon and work your way up. Enemies will get progressivly easier but your team will get more and more damaged and lose functionality as you progress. I hope that hasn't been done to death already.
