OK, scrap the Nebula Device thing. It's a bit shite. On the other hand, I'm really warming to doing a game using an existing engine. This is despite Wookiee's excellent idea, but I don't think we'll be able to write even a simple 3D game engine like that in just 10 weeks.
The only thing with doing a mod is that we need to do something different to be even looked at. What I mean is not a standard FPS game. And nothing Counterstrike-ish either. Oh, and we can scrap the idea of something like Natural Selection too. And not like Midget Wars either.
There are thousands of Q3A and Half-Life modding guides on the net. I've not got any modding experience for either of these engines, but I've done some modding for Jedi Knight and Mysteries Of The Sith, and it's good fun.
I'd still like to do something really original though. A 2D game that isn't a sideways/vertical shooter or a straight platformer would be cool (perhaps even for the GBA). Or a 3D game using an existing engine, that isn't a FPS.
Hmmm.
Anyway, I'm definitely up for doing this next Summer, if we can get a good team together and a good idea for a game.
