Basically you go traveling around the world.
It uses universes and had quite a bit of content, though it still obviously has a lot to be done in it.
I found it interesting walking around it.
The only flaw right now is that there is quite a lot of unfinished countries which sort of kills it to a degree, and I got to a terminal not knowing which country I’m traveling to. Never the less it’s an interesting concept and is worth having a look at.
