wouldn't the hardest thing about switching to a new engine just be the brick stuff? the oct tree, I think? whatever it is that hides the faces you can't see
I mean, I don't know a whole lot about game engines. but almost everything else in the game already exists in other engines, in better forms
even T3D seems like it would be a lot better, and it still uses the same language, right?
like, I know it's not actually gonna happen or anything. but hypothetically, would it actually be that hard??
