As you're blocking the spaces out, once you get to that rough state, are you actually going into an editor and running around in it to see how it feels as far as scale and distances and so on?

Yes, so we're doing that all the time. Despite what we're saying, obviously function is a very important thing for us in these blockouts. Another aspect is obviously making sure that it still feels good to traverse and that we're sticking to all the metrics and stuff, because the last thing we want is to have it make lots of sense but then not be enjoyable. So it takes a lot of time to get that nice balance.
