Some Co op in Dragon Dogma would have been AMAZING. Don't get me wrong The pawn system is kinda cool and if you invest enough time in them eventually they might become effective but it would've have been much more awesome to simply yell out loud at my friends to help me so that we could change strategies on the fly.
Sad thing they wont do it either. Cause I think it would make a series already popular in Japan help reach the levels of Monster Hunter if it was available in portable format with local or online co op play.
