Added VGC, Gamervision, and 1UP's review to the OP. For some reason, VGC won't let me add a plus sign :-/

"Even with some downsizing, Persona 3 Portable manages to be an incredible port of one the PlayStation 2's best role-playing games. Best of all, it adds enough new content to warrant a second look for anybody who played through the game years ago. This is the most compelling role-playing game to come out of Japan in ten years and a must-own for PSP fans around the world. "
GameZone: 8.5/10
"Aside from some graphical downgrades, this is still a solid version of a great RPG. If you’ve missed out on the game before, here’s another chance."
