[@Jeddaven] Late ass answer, but yes, to break down the turn system idea, a GM post will start a "turn". Then people can make their posts and as many posts as they want to, interacting with whoever and reacting to the GM post. Once everyone has posted and agreed to end the turn. Then we move on to "turn 2" which includes a time skip of a few days to a week (or however long is needed), world events happen and individual factions might have a random event happen to just to them. Posting begins again, everyone needs to make at least one post per turn but there's no upper limit as long as two people aren't holding everyone else back.

Also this is more general, but this idea is still open. Might change it a little but I still want to do a post apoc NRP of some design.
