The size and emptiness of that map.
I seriously hope Rockstar are hiding something because that looks pathetic, Los Santos looks smaller than Liberty City and there's only 3 little small towns.
No wonder you didn't show the map R*, you must be ashamed.
If you open your eyes and zoom in you see many other side roads...and look at how large those towns are? They look pretty decent size, Would of been nice to have atleast one more but oh well no big deal...Go into Los Santos City size and you will see how large the city actually is. (If you count the suburbs on the outskirts of the city, Los santos is about 15% larger than Liberty City)
