I've not played through Persona or Persona 2. I have them both on the PSP but I don't have the time to play like I want to right now. If I start late at night I'm up all night playing in bed instead of sleeping. My sister beat the Answer, and I watched, but still haven't done it myself. I played through P3P with the girl and that was a lot of fun.
Persona 4 is a little harder but I think there's more to do in the game and I don't want to give to much away for those that haven't played it, but it is a really good game.
My sister and I played through and be P4 Arena, while it filled in some missing spots it wasn't all that great. It's just a fighting game with really long near book length cutscenes you have to read. As a fighting game it's good but as a Persona game isn't not what we've come to expect from them.
Since we all seems to be atlus lovers, has any one played Catherine? I love that game, it's a great waste of time over all, but it's nifty in the game play of it actually.
