I’m sure everyone has looked up something in Wikipedia at one time or another. Kevan Davis, a developer in London, has developed a Wikipedia game called Wikipedia: the Text Adventure.
You choose where you want to start and it brings up information from Wikipedia. You can choose one of the locations offered or put something in. You can then choose where to go from there from the offerings it gives. You would type “go ” and then the direction choice from the list. Example: go northeast.
To leave and go to another adventure, you would type exit then yes. Check it out: http://kevan.org/wikitext/
