Some theme ideas:
Triangle/simple shape - something substantial revolves around a simple shape
“alice in wonderland” - has to do with the main character going to sleep, traveling through a portal, or some other way, getting into a strange alternate dimension. Doesn’t have to be a character game, it could be a puzzle game, or a racing game, or anything, as long as it has that strange world alice in wonderland feeling
altered reality - similar to the last one. Everything about the world the game takes place in is mostly set in modern times and based on reality, but there is ONE substantial thing about this reality that is obviously different from our reality
SPEED - everything about the game makes your adrenaline run, and is really really fast:)
Care - the game has a slow pace, because you have to always be wary of what may happen. Death lies around every corner, one false step could be your last. A racing game where crashing into a wall eliminates you, a fps where enemies kill you in one hit; you have to be careful to survive the experience.
At the end of this contest, we can vote on a new theme and start a new contest immediately.
granted you need at least a P500 with a reasonable graphics card for blender to perform. But if you want a game that involves SPEED check out (plug ) tunnel pilot3 from my site
