ugh not this again.
terrain can be endless and smooth for vehicles for almost no performance cost. do that with bricks please.
interiors are pretty much useless tho besides like being a lego.
I agree that they can be endless, and that they are much more efficient for vehicles. But better vehicle physics have a strong possibility of being added after v21. About them being endless, I don't really see that ever being really put to use.
What do shadows add to gameplay? Bricks already exist.
And interrains aren't bound to the grid and can have "odd" shapes that aren't first turned into bricks.
Shadows like you said are just cosmetic, they make builds more appealing. It's true they won't add anything to gameplay, but it's a nice touch and can encourage people to build more. GSF is working on terrain bricks, no matter how bad the textures look, but will provide you your "odd shapes." But bricks can still provide a destructible environment, and can be evented to do all sorts of things.
