@ Govedo / Generally everyone:
You have no idea how hard it is to balance the economy right.
It's one of the reasons why my 40% done plugin of dynamic economy probably would never be implanted in the mod, too.
Anyway, as for devs being with their head up their behind, I have a suggestion for you - be a dev yourself. It doesn't take much, really. Just do some stuff, show it off and viola - you are a dev.
If you think their work is so easy, I suggest you go and do it yourself.
As for the OP - While I am not totally against the idea, I suggest you both take advise with a storyline dev and with Xoria (economy guy). Good luck.
