Wikirunner (aka Wikipedian Tag) is a go:
Wikirunner is a game played on Wikipedia articles. There are two players: a runner and a chaser. Both start on a random article; the chaser’s goal is to end up on the same page (at the same time!) as the runner. The runner is simply trying to evade the chaser for as long as possible. You can play it single player, as either player, or hotseat with a friend. Woo! It’s based on Jeremy Bushnell’s Wikipedian Tag rules — be sure to check him out as well.
I spent the last two hours or so giving myself a crash course on python threads, and re-writing all my internet code to be asynchronous. I’m certain this was a good use of my time, too — the little throbber that flashes up while it’s downloading from Wikipedia is so very worth it. Plus I have (tentative, indirect) permission from the author of the ruleset I’m using (‘Wikipedian Tag’) to re-use it here — something I need to actually obtain, as it’s licensed CC-BY-ND, and this is pretty clearly D.
