I have a strong attachment to Cosmo Canyon; not because of the narrative events but rather that this was where I spent a considerably large chunk of my playthrough grinding. The reason? HP Plus Materia.

You see, when I was younger, one the most important things to me in an RPG; any game really, was having really high HP numbers. I would stay here grinding away for what felt like dozens of hours until I had levelled each to near max level. By the end, Cloud was at level 50 before I even entered the 'Cave of Gi', and the rest of the game afterwards was a cakewalk, in comparison I was around level 30 when I got to Nibelheim on this playthrough.

Speaking of I quite enjoyed the puzzle involving cracking the code to the safe in the mansion, almost makes me want to forgive how awful the encounters in this place are. Yet again I must iterate, that the worst thing an enemy can do in this game is waste time, and oh boy...there are no shortage of them here. The ghosts that all manage to get a turn off before you can run away, that guy on a chain that keeps fucking falling over and wastes time trying to get back up (seriously what is the point of that?), and the worst of them all: Yin & Yang. Square(soft), I hate to inform you, but I don't in fact enjoy having to watch an enemy take 20 seconds to do an attack.

On a more funny note, I like how you can infinitely take Tifa's life savings from the piano.
