I have never beaten a single Final Fantasy game despite loving FFVII, VIII and X at the time.
Got far in FFVII but didn't have the 3rd disc I think back on PSX. I then started it on PSP years later through emulation but while playing my girl at the time texted me to break up and I never played it again.
FFVIII same thing didn't have the other discs(didn't have money to buy games when I was a kid).
FFIX-I never played it when it came out. I started it up a year or two ago on my retro pie but didn't get very far in it.
FFX-When it came out I didn't have a PS2 yet(Had a Gamecube). I then had a PS2 years later but when I got the game through rental I didn't have a fukking memory card
I got to some plant boss in a forest and died and the game only allowed me to start over or load game
FFXII-Never played it.
FFXIII-Rented from Gamefly for PS3 and got to Gran Pulse and had to return it. Never played it again.
FFXV-I just stopped playing it due to backlog of other games coming out. I got like 10 hours in I think. It's okay but not as great as the other FF games imo.
I never played the earlier ones either.
Actually the only square enix games I beat were Kingdom Hearts 1 and 2. 3 I haven't really touched since Jan Feb last year.
