Putting this here for record-keeping:
Just finished Final Fantasy 3.
The significance of this being: In 2013, I had started my project to play all of the mainline FF games. Although I did beat most of them, there were several that I had almost beaten, but often these games will get you to the last dungeon and you need to spend days doing boring level grinding in order to defeat the final boss, so I just burned out and said that I was done when I really wasn't.
So although I "beat" them, it always bothered me that a few were actually unfinished.
This one was the last one, so I can say (without lying) that I have fully completed FF 1, 2, 3, 4, 5, 6, 7, 7R, 8, 9, 10, 10-2, 11, 12, 13, 13-2, 13-3, and 15.
(14 doesn't count because it is going to take some more years for them to finish the main story, but I am following it as they release new content).
So hyped for FF16 and FF7R Part 2! I was thinking that if they really do a full trilogy of FF7R correctly, then as a whole it WILL be my favorite game of all time, no questions (while currently it's hard to choose a favorite).
