General Game Advice!

[emeralddarkness]

I am currently in the process of developing a limited-run limited-cast game based off of Tam Lin and the other old stories of Faery, focusing most heavily on the Tithe. So I have my idea, I have my plot more or less plotted out, I'm developing my npcs, I've got my world mostly figured out. What I need are things like advice on where to advertise, or what - from an ooc standpoint - every good game needs (like as far as ooc info or lists or anything), or how many events is too many and how many is not enough, or how involved should NPCs be, or where to go to look for mods or coders. Basically general behind the scenes info - the 'what I wished I'd known when I made my first game' type.

Anybody have any advice?
