How bout most of the map? There was far too much countryside, which granted added to the realism & was proportionate to the scale of the cities, but it wasn't as fun a playground as the urban settings. What R* have done is spot on, focusing on quality & not quantity, I'd take a smaller city that I can really interact with over a huge sparse map any day.
right, luckily this time R* made a city with no vast wasteland... yet almost large as SA
