I remember them saying that you could fit the RDR map 5 times if you included the underwater locations. Checking the above comparison shows that you could probably fit 5 RDR maps on the island anyway with room to spare so I think the comparisons wrong. The whole island is big enough, I'm just talking about the city. I guess I'm so used to it after playing GTAIV that I want more city to the map.
