The more honest fan question is whether interiors feel like part of the street. A store, a gym, a club, a motel, an airport - that is already a better menu than GTA V's 'this door is a texture'.
What the footage actually puts you inside
Convenience store, airport, nightclub stairs, elevator, gym, motel, homes, offices. It is a spread, not one hero interior they filmed for a year.
A trailer can still cheat. Mission-only rooms have been a Rockstar tradition since forever. I am hoping the boring ones - corner stores, apartments, diners - stay unlocked when the yellow marker is gone.
Why 'every building' is a trap
Enterable does not mean good. If they clone 400 empty shells so a YouTuber can count them, the city gets worse. I would rather have fewer rooms with stuff on the counters and people who get annoyed when I walk in with a rifle.
GTA dreams are always bigger than GTA budgets. Judge the doors they let you use, not the ones a Twitter thread imagined.
