Noga, cool!! I have neve seen another engine similar to C2. Do any compare in quality?? I'm also in love with C2 and the community, they have a really good community.
If you want to try it, I'd start with Starcraft 2 editor (War3 is too old now). You can look at
where the guy is working with the editor. I like the easiness of both (SC2 and C2) program editors. I prefer C2 of course<img src="smileys/smiley1.gif" border="0" align="middle">, because you're not restricted to SC2 world (you can mod, skin etc., but that's huge amount of work) and SC2 players, and most importantly, I can sell my game.
