@butterdog @MachineMadeDog @Curvin to do it well you need a shitload more art than usual, and your engine has to be able to handle huge variability in loading and draw distance, which isn't a common feature

there are lots of compromises you might make to mitigate those problems but making the right choices is itself very difficult and can be risky in terms of development effort (you realize you made the wrong choice, but have a ton of work sunk into it)
