With all due respect (very little), most of the world that you can live in has been lived in for thousands of years, and you will always have to deal with the fact that you'd like to live there too.

We can't just exterminate everyone to make the world a lovely museum and, if you want to see level 11 of Crete, you're going to have to go through the 23 levels above it first, anyway. London, Paris, Athens and Rome are built over such incredible history, you have no idea. That goes for about everywhere else as well.

Record what you can.
