I just unpacked my games and this is on the top to replay.
I'm with threetimes though. I rather liked the way the game played. I've done both the English / Western version and the Japanese version (and yes, there are a couple differences that I remember) but grid or not, the gameplay is fun if you remember this is NOT a PS 2,3,4 type game and not to judge it by today's standards.
I find this game still holds up better than most and, along with my Shadow Hearts games, tops my favorites.
