Firstly, it's pathetic to avoid a game because you can't use a trainer. All the work the developers put into it and you don't want it if you can't cheat.
Secondly, you don't need trainers for Final Fantasy games. Using them for the main story is cheap and cheating on side-quests and mini-games is just plain stupid. RPGs are built around improvement. You level up and get stronger, you put time and effort in to gain skill. Why cheat and rob yourself of the experience?
This is spot on, FF is a game to immerse yourself in, it doesn't need a trainer. You're really missing out.
