Having sat down and actually put some time into it, I have to say it's not as bad as people seem to make it out to be. Yes the game has it's flaws, and some may be prominent, but I don't view any of them as game breaking. As long as you can install the game the main issue, the battles, become alot less bothersome, there's still a little slow down, but not nearly as bad as without, the issue with textures popping, while noticeable, isn't as bad as I've seen in some games.
All in all I definitely say the games worth a rental for jrpg fans, and if you can look past the faults you can easily milk a lot of game time out of this. The story's not too bad either.
