It could be some magical combination of factors including stars and planets in the right alignment or some other cosmic hoosefudge, but I certainly did NOT expect to enjoy the game as much as I did. I've complained a lot about JRPGs in various threads and not only did I have none of those complaints here, my expectations were thoroughly exceeded. Of course, this is Atlus in-house and we're all Megami Tensei faithful.
So far, in scouring the web, reviews for the game have all been favorable. I don't think any other critics liked the game as much as I did, but all scores are well above average.
Regardless, I hope that whomever gets Radiant Historia this week enjoys it at least half as much as I did.
