Ok, so about 2 months ago, I beat Resonance of Fate; the story was a little silly and dumb, but it was still a great game. After beating the main story, I went into the super secret dungeon NEVERLAND, which just happens to be an amusement park (no MJ jokes please). Secret dungeon is hard as hell the first time; I beat the main story at level 80, and by the time I beat the final boss of Neverland, I was like 180. So the game is all done and dusted.
 
Then I got into my head to play it again, sweeping up all the achivements. But I barely put any time into my second playthrough. I just spent my time, in my previous save, GRINDING IN NEVERLAND DESPITE THE FACT THAT I BEAT THE SECRET BOSS ALREADY. The battle system isn't even that fucking complex to warrant such playing, and I've probably seen every single animation a million times, but I still PLAY IT. I've beaten that final neverland boss like 5 times by now, and I still keep playing!
 
HELP! also has this ever happened to you? I don't mean "yeah I kept playing CoD" or something, because that has an online component. Played a single player game over and over despite beating everything in it?
