Linkrunner
Alright! This is a totally kick-ass theme (thanks, GirlFlash) and I’m glad to see lots of people running with it. Too bad I’m not one of them, though — this is just about the most straightforward Wikipedia-reliant game you can imagine. There are two players, a runner and a chaser, each of which starts out on a random page. It’s basically a game of tag with the chaser chasing the runner through article after article. The chaser moves faster, but the runner has complete freedom to duck into “Lists of Phoenician Rhetoricians” and hide all night, if they like.

It really just looks like a two-player browser, doesn't it?
While technically two-player, you can only (at the moment) play as the chaser against a simple AI runner — I’m currently trying to figure out how to adapt an existing bit of code that calculates the distance between two phrases (actually, my PhD project truth-be-told) into this without making you download ~80gigs of word-vectors.

Still, I can’t help but feel that the runner has a huge advantage.
