Ok, one of my biggest pet peeves is people loading up my NDS and fucking around with my save file on a game, especially when there are two or more open save slots. My older brother took my DS while I was sleeping this morning and started playing it, that doesn't bother me, but I turn on my DS, load up my FFIV (J) save file, and find out I'm onboard Golbez's sky tower! I fucking saved it outside a cave last night.
