I think the ending of the Requiem of the Goddess DLC for XIII-2 was the only one. Serah's goodbye just wrecked me completely, and I can't even fully understand why. Dammit, Square Enix, you always turn me into a little kid with your games. xD
XIII and XIII-2 made me tear up. They hold a dear place in my heart as my first true final fantasy games and the stories really touched me. The individual characters and their back stories was just so interesting to me. By the end of both games I had grown to love all the characters and when they are nearly defeated by the end bosses it really made me want to play on and win! gaia_kittenstar
Final Fantasy X ending. My first game and I had honestly thrown myself into it.
Crisis Core for sure. Couldn't stop bawling.
Many times throughout 13 and 13-2. Oh gosh. Especially the ending of 13-2. I knew it was coming because I was spoiler-ed T.T but still- it was so upsetting.
