Will there ever be less invisible walls?

[Skivvy]

Can you name any that don't also have the same kind of invisible walls where you can go everywhere you can see?

As mentioned, GW2 is pretty open, and then there is also Archeage. With Archeage, you can pretty much climb/glide/explore anywhere you like. It was really quite a lot of fun just exploring and trying to see how you could get to the top of whatever random landmark you felt like. I'm sure there are plenty of others, my gaming experience if fairly limited.

Then we hop back over to XIV where even tiny little puddles have walls around them (I'm looking at you Western La Noscea).
