Why on earth would you list all of the Final Fantasy games in one spot when they're all so different? Who cares if your top 5 winds up being 5 Final Fantasy games? They're generally diverse enough that it still shows a pretty broad taste in jRPGs.

For instance, I really liked Final Fantasy 9 but found 8 to be tedious and 7 to be too primitive. Final Fantasy I and II haven't aged well at all (II in particular was a tedious mess) while IV, V, and VI are still fun even with the technical quirks of the PS1 ports. Final Fantasy Tactics' battlefields were a bit cramped and the localization was awful, but it was still a joy to play. Chocobo's Mysterious Dungeon was poo.
