Deep RPGs That Are Better The Second Time Around

We all know that feeling: So many games, so little time. That's the reason for titanic backlogs, really, and why buying games and playing them are two entirely different prospects. We're often lucky to play a new title to completion, especially if it's a lengthy and involved one like an RPG. This is such a shame, because sometimes, it's in a second playthrough (whether new game plus or otherwise) that a title really shows what it has to offer.
