This reminds me that I still need to beat Xenoblade and Pandora's Tower since I own both of them.

Anyways, I won't be able to accurately judge what modern Final Fantasy is missing until XV comes out. All of the Final Fantasy games since the PS2 era have been vastly different games. Each of them have their shortcomings or things that don't match my preferences, but those shortcomings are different in each game. If I were to choose anything that's missing, it would be Nobuo and nostalgia. Even then, the music isn't bad, I just like the older soundtracks much better.
