Ight... I found these to be the most annoying or challenging sidequests in FFVII-FFX. I left any others out considering I haven't played FF-FFVI in the longest time. For most annoying SQ, definately the Card Queen in FFVIII or Cactuar Stones in FFX. As for challenging, getting the Excalibur 2 was a bitch. The first time I tried, my gameclock was 12:00:03... as you can guess, I proceeded to throw my controller against the wall several times. Then I went back and did it in 11:56:04. I'll set the poll for more than one option but don't try to screw the system.
