Incorrect. The one time I got to 299, I went around for hours looking for more missions, and that was the only mission I hadn't done yet. Because I had missed whatever mission gives the Eldagusto, I couldn't do it. When I restarted the game, I made sure I did all the side missions that pop up between each storyline mission, before advancing, and I got both the items required for that mission. Once I did that one, I advanced and got all 300, unlocking the final quest chain where you get cid.

I wasn't aware that there were 4 different reserve missions, but I have played that game a hell of a lot.

And the thread is talking about FFTA, not number 2. At least that is how his post reads.
