Since i ant pick MMOs and its among my top3 genres i'll go for RTS style.
Company of Heroes or DoW 2. Could just waste time polishing the multilayer skirmish skills, cRPGs as far as they are fine, during a year period i'd be to familiar with all the plot gimmicks to really be able to enjoy it, and lack of multilayer would just make it really boring. RTSes on multilayer however would at least give some form of social contact to not go insane.
