Most of the time spent in the final fantasy games was not in dungeons... at least not in the ones I've played (FFIV, FFVII, FFX, FFX2, FFCC, FXCCRoF, FFT, FFTA, FFCD, FFMLAK), but instead travel and grinding travel for XP.
And a few, the dungeons even are open terrain and not a classic railroady dungeon. (FFCC...)
The dungeons in FFIV were major plot points but not the majority of play. IME, both as player and watcher, FFIV, VII, VIII, and IX all seem to hold to that, as well, and several of the odd lame GBA/GBDS titles were mostly travel and town with no dungeons before I got bored.
The town sequences in many are just as much a time sink as travel.
And in FFX, the blitzball...
And some others, outside the FF line, such as Octopath Traveller, are likewise town and travel heavy.
Only in Chocobo's Dungeon has it been heavy on the Dungeon time.
And those are all ones adjusted to western sensibilities.
I'll note that MLAK is all about dungeons, but the player never enters one....
