Don't bother with 1-6 just emulate if you must play them.
7 is an ANCIENT windows version that looks sounds and runs like shit
8 remastered is okay but some of the upscaling looks terrible
Emulate 9 as its a port of a port (psx->mobile->oc)
Final Fantasy X/X2 is okay but the upscaling again is off in places
Final Fantasy XII is a good port but the game doesn't feel like a final fantasy game, its feels likea single player MMO
Emulate the PSP version Final Fantasy Tactics, it has a bunch of content the remaster doesn't
