Sure, causing havoc in the city is fun. But you can only spend so much time in the city before you want some open countryside or a nice suburb to play in. GTA V should at least give us one of these. Perhaps opening up the large mountain range in the picture above would work? It's always nice to have a way to escape from the city, and adding an environment that isn't a bustling metropolis would be great, especially for multiplayer. The ocean doesn't count.
