The zodiac version of 12 is petty good mechanically.
The whole point of these games is an over the top story, 12 is just basic fantasy tropes, nobody has amnesia and the world isn't destroyed or ravaged in some way. There's no plot twists really.
4: You go to the moon? Haven't finished this one.
5: World has been split in two and you merge the two halves to get a new world map.
6: You fail and the world ends, you can only take revenge for it.
7: Giant kaizus start destroying everything and there's a giant meteor about to extinct everyone.
8: Time is stopped and you need to travel to the future to restart it.
9: Erm... it gets misty?
10: The world ended a thousand years ago and now the survivors live in a polynesian tropical island Mad Max Waterworld.
12: Some guy won a war.
Kain is mind controlled, Galuf has amnesia, Terra has amnesia, Cloud has amnesia, everyone except Irvine and Rinoa have amnesia, Zidane and Garnet have mini amnesia, Tidus is a dream and Auron is a zombie. What does 12 have? An evil twin? Meh.
