Games I found disappointing include:
FF8
- The story was terrible. From the love story, to the SWERvE~! of everyone coming from the same orphanage, the junctioning/drawing magic system, and the terrible final boss, the game just sucked on all cylinders.
FF9
- I don't know why, but the whole story and gameplay were just simply boring. The only good thing was having moogles act as save points.
Sonic Adventure 2
- I don't know how, but the collision detection in SA2 was worse than SA1. Add to that the fact you have to play as a character you might not want to play as, and several freakishly hard stages that require you to take a leap of faith with the collision detection...I just didn't like it very much.
