Listen, JJ3 ruled as it was. The demo was IMO addictive, with nice graphics* (look, they worked on it when JJ2 came out!), a good plot (hehe, I never saw a game where you have to save your children), and the gameplay was nice (much puzzles, I like puzzles). If Epic would only give us the JJ3 code and permission to use the engine (They will never do that, anyway)...

About your idea: it won't work. You can't organize a good game making project with people on the other side of the world. It simply won't work: maybe if we already got an engine etcetera...

So sory for destroying your dream.

*If you check the options in the rigth way. The normal settings mean evil gfx.
