Super Pokemon Mystery Dungeon actually has the whole world map of red/blue rescue team and explorers of sky in it.
MGS4 has the whole world map of MGS1 in it.
While maybe not counting, Dead Space 2 has the ishimura of Dead Space 1 in it.
One of the castlevanias has the whole world map of a prior one in it but i can't for the life of me remember or google which

Awesome, thanks dude. I'm wracking my brains trying to remember which Castlevania it is

yomawari Midnight shadows has the entire map from yomawari night alone in it

Disappointingly, the map of Crackdown 2 was actually the same map as the first game, just with some damage on the buildings.

I think Far Cry Primal also uses the same map as Far Cry 4 though how much of that is intentional lore and how much is lazy design is up for debate.

golden sun 2 may fit onto this list but its been so long so i cant say for sure someone else confirm this

DoesMarvel’s Spider-Man Miles Morales count? The reason I ask that is because it is a half sequel, but has the same map of the 2018 game in it

Ehhh, I feel like expansions like Miles Morales don't really count towards the spirit of the list, if you know what I mean. Same with Far Cry Primal and Crackdown 2, although those are even lazier

red dead redemption 2 also has the entire red dead 1 world map in it

Red Dead 2 doesn't have all of Red Dead 1, it's missing Mexico.

nah dude it's there https://www.youtube.com/results?search_query=red+dead+2+mexico

That's a stretch lol

Danganronpa 2 has you go back to the school from the first one
