The world of Final Fantasy IX.
Firstly, it still looks stunning today. The art direction for this game is absolutely superb, and I've never played another game where the world feels so large, and yet so cohesive, and utterly, bizarrely beautiful at the same time.
Not only is the world amazing to look at, but Squaresoft did an amazing job with the lore.
A lot of other games, especially RPGs, tend to lay the lore really thick and heavy. Any chance the writers get to show off just how much background
stuff they've written, they'll happily bog you down with exposition about the history of this faction versus that faction, or the royal lineage of this kingdom, yadda yadda yadda. It's a really leaden, dull way to convey lore, I find.
The world of FFIX has lore. Plenty of it, in fact. But the developers never burden the player by walloping them in the face with a load of it. The lore of FFIX isn't told through cutscenes, or extended database entries. It's told through the actual gameworld itself. So you may see a statue dedicated to a character here, or a recurring symbol there. Characters might mention a bit of local history just in passing, or a recurring name might appear on key items. But actual lore exposition is kept to a minimum, which makes the world so much easier to get into. The world is presented to you, and if you want to know more about its history, it's up to you to go find all the details Square hid throughout the game. It's possible to get a surprisingly dense, rich and consistent sense of history in Final Fantasy IX if you look hard and see all the little snippets of info scattered everywhere.
