I play a lot of JRPGs, and I must say that I see Type 0 fairly often when I'm shopping for games and there have been countless times when I have thought about picking it up. The review scores make me hesitant, however, I enjoyed FF13 very much despite it's less than stellar reviews.
I still need to finish Lightning Returns, which I started several times but never finished it (I think as far as I got was day 8 or 9 possibly (having done two or three of the major story arcs).
