I recently bought Adeptis Rahn. one of the best looking minis ever imo. I bought this purely at the fact that it looks epic and could be fun to paint up. but have never played warmachine and I dont know if anyone in my area plays it. so before I commit myself to an army and buy, I would like some info on what its like to play, what are the factions, will it grow to 40k size, will I enjoy it and are The Formula P3 as good as citadel or better?
