However, IGN's statement comparing Los Santos to Liberty City refers only to the city limits. Though presumably Liberty City includes Alderney (since even in the game it's barely treated as different).
If, all of these given facts are true:
- IGN has said the map is about five times the size of GTAIV.
- IGN has said the city of Los Santos is about the size of GTAIV.
- GI has siad the world of Los Santos is bigger than GTASA, GTAIV, and RDR.
- The non-city part of GTAV is the size of 4x GTAIV.
- The non-city part of GTAV is larger than RDR+GTASA
- RDR and GTASA together are smaller than 4x GTA IV
