I have been interested in making a 4X game myself but never got it off the ground... though I do admit I am rather choosy about my programming Languages, which one are you using? I just couldn't make myself do anything but C#... ok, maybe VB or possibly C++, but C# is so cool
But aside from programming, I could help with other things... I always have lots of ideas, not just vague suggestions like "needs more aliens" but ones that I can state concretely with numbers and things... "the scanner ranges should increase exponentially by 10% a tech level" or something...
