FF14, WoW, ESO should be more accurately called MORPGs or multiplayer online RPGs. They're no longer massive compared to popular and award-winning modern open-world RPGs like Elden Ring, Assassin's Creed Odyssey (yes, it actually won a few GOTY), Skyrim, and upcoming ones like Starfield. You can fly from edge to edge on a modern FF14 map in just under two minutes today. Compare that to Assassin's Creed Odyssey, which takes 10 minutes on a ship much faster than FF14's mount. Keep in mind this does not mean Odyssey is 5 times bigger than FF14. It's 25 times bigger (you have to square it).
But just having a big world is also not enough. I mean, there's a reason why Ubisoft games which all have super large maps are derided, although I think Odyssey is still the best of the bunch. It's about density as well. And FF14's maps just have nothing going on in them. You can fly half the map in Azys Lla and not encounter anything interesting. Compare this to something like The Witcher 3, whose developers have mentioned that players should encounter something interesting every 40 seconds (https://www.youtube.com/watch?v=T3btOwctl9w). But you can easily go 40 seconds on an FF14 map without encountering anything interesting. Worse yet, an entire map could be almost pointless in FF14, like The Lochs or The Peaks, where you never visit it other than for the MSQ.
I really hope the next FF MMO puts my effort into building a better, denser, and bigger world. FF14's worlds are just not it.
