Nearly every single remake/port of a Final Fantasy game onto the GBA, DS and PSP. Most due to a lot of renaming and petty things.
Magic being turned in to..Magick..because it's more fantasy I guess?
Changing it from something like Fire 1, 2, 3, to Fire, Fira, Firaga (A trend I never really liked since they first started doing it). Taking from FFXI as well and making the status effect spells like Antidot into the -na suffix spells, like Poisona.
Fixed names, changed dialog..all these things I spent years knowing and loving , picking them just felt..awkward, even though it didn't actually really change anything beyond the surface look.
