Well, U should... U MUST be our project manager and eventually the musician for mod and sfx.
The musician work require a rather limited work compared to the code and graphic tasks... but, if they' re not only one music (not only the same 4 the whole game ( options screens / battles / congratulations / introductions...)), we will need one or many others soundtrack musicians.
Now, we should try to chat about this project on a mailing list (I've read before that there was a webmaster among us... Could U manage this ?).
Furthermore, many of U should deals with tis project on many ATARI news groups/forum to bring more members in our development team.
Kingdoms of England could be a good basis.
But before all, it's to U/damir 2 describe fully your game (background, ideas, technical management...) and we will decide if starting a new production is better or not.
