This game is seriously incomplete, and I'm not talking about the glitches, or the dialouge that seems seems to have random moments of voice overs that were recorded during different times of day as each passage has a different tone of voice. Well what saves this game is the grid system. I'm still playing it, honestly I couldn't put it down since I got it yesterday and I'm 24% to completion. This might seem contradictary but I haven't played an RPG is a long time and somehow this thing full-fills my needs and desires.
Yes it's a quirky game, yes it has random battles, and is not a masterpiece of a game by a long shot. But what made me really enoy this game is the fact that I've played through a quarter of the game without once stopping to just level up. If your clever you can win every fight without needing to save. Although it does help to up your stats if your clever and most of all patient you should be fine in any situation.
Some additional words of advice; if you have weak hands, than don't play this, at least not for long periods at a time. The shacking sixaxis gimick is well overdone and I swear my hand is numb after constantly doing the boogie, than pumping up the special attack, and than doing the boogie again (you'll know what I mean if you decide to play).
Well I could go on and on. Basically speaking it's a game without competition, and you would probably have more fun playing a PS2 RPG since the graphics here, well hey .. that's in the eye of the beholder.
