what you can do underwater is extremely limited...
the amount of time/resources they wasted on making the underwater in GTA V, they could've made other cool towns or cities in GTA V.
I played the GTA V story line, and aside from the missions underwater, I did not dive/explore the ocean.
The GTA V map was big, but it was filled with nothing, outside of Los Santos. The forrest and natural landscapes were dissapointing.
That small town up north on the map, what a useless idea. there was nothing fun to do there. instead they should've made two equally big cities. Lost Santos + another big city up north, and then forrests, mountains, deserts, jungles and oceans in between the two cities.
The GTA V map was dissapointing. Hoping GTA 6 has a better map including more than 1 big city, and plenty of detalied nature (forrests, jungles, plains, deserts, etc.)
