Figured we needed a proper mapping thread for Leonida before the next info drop buries everything again. Idea is simple, we go through every trailer, screenshot and postcard R* has put out and try to pin down where it all actually sits.
What we're fairly sure of so far: Vice City is the anchor, Port Gellhorn is the west coast city, Ambrosia and the lake are inland, Keys run down south. The two big question marks for me are how far north it goes past Mount Kalaga, and whether Gloriana is real playable land or just set dressing.
Post your reads, your overlays, whatever tinfoil you've got. Nobody's right yet, we're all guessing.
