Then there are some games that I'm playing but in very small bursts, maybe playing them once a week for a few hours at most. In some cases I've only played them once but, supposedly, will carry on at some point. All on the Wii apart from Persona 4. I've completed the first two games but am now on a New Game+.
One Piece Unlimited Cruise 2 (NG+)
Persona 4 (NG+)

Seriously considering replaying .hack//GU but apart from that, nothing.
