I am mnot an average gamer and after reading some other posts it seems that normal is not a good place to start for people that don't want it to be a really easy, quick game. So... What level do I start at? I Am reading nightmare? Opinions? Also what is the progression path? Do I complete it on a certain level then it restarts to the next difficulty stage? Do I collect all the best tier gear from that difficulty level and then move on?
Thanks for responses!
