What a creative idea! This game pulls information from Wikipedia in order to build a game world for you to explore, roughly positioning different locations as "rooms" according to their geographical markers. I typed in the names of a few places in my city and had fun "walking" around the familiar locations for a little while.
The HELP command gives a lot of useful and amusing options for interacting with the world and system.
I was especially excited to find that (Spoiler - click to show)typing XYZZY actually has a response!
