it took me hours to drive around GTA4. Jesus Christ.
This'll be fun when you're on one end of the island, and you have to get to the other end.
Or worse, "Kill the target" on the other side of the map, and he's fucking difficult to get, so you have to redo the mission a couple of times. Which makes you go back and forth a couple of times.
At least we now have planes.
Still, remember how boringly dull it was to take a jet and fly from Los Santos to Las Venturas? Now remember that GTA V is at least three times bigger. Imagine flying from one end to another end.
(I compare to SA because I played SA way more the GTA IV, and the maps are about the same size)
I think that is part of the driver behind the "3-person switch" gameplay. I'm guessing it will be faster to just switch to another character who already is on the other side of the map.
