"Papers, Please", of course... I'm not worthy of glorious arstotzka.
When I first heard of Passport Please I was reminded of "Neal Stephenson - Error": the story contains a MMORPG which is used to "automate" stupid security tasks like screening people at an airport by "mapping" them to the MMORPG world were players are awarded when they detect a security threat. I hope this never becomes real.
Available DRM free for Windows, Mac and Linux on GOG. :)
I think I've once seen a service, which collected detailed information about the passports and other identification documents from all around the world and provided access to this over the Internet (probably in exchange for nice amount of $$$/€€€ per month).
I just can't remember the name of the service and also can't figure out appropriate search terms.
