I like to play them, but the grind sometimes gets to me, also I have a bad habit of overwriting the same save game, which if you save in the wrong spot, like right before a boss battle, and then you find out that your characters are to low level then your pretty much screwed.
That's what kept me from finishing Final Fantasy X, on second thought that's what kept me from finishing most JRPG's I've tried to play, I'd back myself into a corner where the only viable option would to be to restart the game, I don't learn do I?
