I just bought Final Fantasy IV Advance on GBA today, which is the first time I've played that game in about a decade. It reminded me that when I was younger, on my original SNES cart, I leveled up Palom and Porom until they could cast Holy and Meteo. It took an unbelievably long time to do this. (I still have the cart with that save file on it, but I'm afraid its battery will die in the relatively near future.)
Thinking about this reminded me of all of the other obsessive-compulsive stuff I've done in RPGs, mostly SNES ones. These things range from minor like beating the Emerald and Ruby weapons in FFVII, to getting the Sword of Kings for Poo in Earthbound, all the way to beating Earthbound in Japanese (I don't speak any Japanese) without using a guide or a walkthrough (let me tell you, the monkey cave was a bitch) or getting four economizers in the dinosaur forest in FFIII. Still, I think teaching Palom and Porom Holy and Meteo takes the cake.
I'm sure I'm not nearly the hardcore RPG player (or gamer, for that matter) of many on this site, so what weird crap like this have you guys all done? I especially await someone with related Disgaea stories--that game just begs for it.
