I dare anyone to compare this Cosmo Canyon side area field to literally any field in FFXVI and see how many layers of interactivity are at play
If you've never played Rebirth or even watched it then you might not see anything just by looking but there's well over a dozen elements to every single area and they are almost always unique.

Multiple layers of interconnected verticality exists across this field and can be reached through a combination of on foot and through the air traversal
Jump pads on the ground launch you up for Chocobo Gliding
Balloons keep you gliding while airborne
Moogle Emporium is tucked away up high and off in the distance. How do you get there?
Lifespring fountains tucked in little oases
Summon crystals down in caves
Gilgamesh side quest mini game in progressing difficulties placed throughout the ruins
Runways are placed at various elevations to glide back down from
Reaching various elevations requires puzzle solving and paying close attention to the level design and flight paths
Then, tucked away over there in a corner, is a little ol' tower you can climb to see more on your mini map
Then there are various fodder mobs are placed around the map to fight, often directly taken from the original games area
Then there are various mini boss challenge mobs are placed around the map to fight, also often directly taken from the original game
Then there are hidden Chocobo treasures and crafting recipe to dig up
Then there's a Yuffie side quest marker to do a Chocobo Gliding mini game challenge
Then there's multiple other characters' side quests, that all take you throughout the field naturally while building up the characters personalities and relationships
