The fourth picture with the huge lake, wonder if that is going to be fully explorable, or is it just the coastline? Ohhh can't wait to fly a seaplane over that mountain and land on the lake.

By the sounds of it it'll be pretty much the whole surrounding areas of water that will be fully explorable, so yeah. Obviously there will be some invisible wall that will be reached at the edges of the map though.

maybe not. remember in San Andreas you can go out as far as you want, you just wont find anything. (And I think in IV too)

I was never a big fan of swimming in either Gta's so i could really careless about the sprawling lake and oceans you can explore and dive in. I just want customizable guns and cops that will try to arrest u if u shoot somebody in the middle of nowhere
