I'd say for me, it had to be FF12. I thought the game was going to be so much better than it was. I was a fan of FFX and FFVII and when 12 came out I was jumping for joy.
Then I played it.
I couldn't believe they called it a Final Fantasy game. Its was more of a mild scifi/fantasy hybrid and it wasn't very impressive to be honest. The music was boring, the characters were boring, I couldn't get into the story. The combat system was automated. The story talked too much about people I hadn't seen, and half the time I didn't know who they were talking about, and none of the people in story seemed to have had much to do with what you were doing. They most interactions characters had between eachother were the few cutscenes explaining what was going on. They game had vast amounts of wasted potential.
FF13 did come along and fix a lot of the story issues, but then they threw the combat system down the toilet by making combat entirely "autobattle", making it so your level locked to certain chapters of the story, no exploration, hardly any side quests, and they story was still missing the hook to keep me interested, but I had zero expectations for 13 so I wasn't upset.
I guess I had too high of expectations for 12, and it wasn't made by the same dev. team that made FFVII and the others.
Any let down stories you guys have?
