Katharine Neil, a long-time game developer who worked as a programmer (not, I suspect, with great enthusiasm) on the 2008 Alone in the Dark, but whom Play This Thing! readers may know better as the voice behind Invoke, the satire of Jane McGonigal's Evoke ARG, brings us Alone in the Park, a sort of text/graphic adventure hybrid.
The unnamed protagonist finds a letter in her -- basement, apparently, from the image -- that invites her to enter a nearby national park on a scavenger hunt for treasure map fragments. Being a gamer, she of course immediately sets off to find the nine thingummies of whatsis, and naturally, everyone she encounters has or knows where to get one, but insists that she embark on some sort absurd quest (ranging from "bring me the six gizmos I scattered around the park" to "get me a date") before they'll release it.
So far, so cliche'd, but of course Neil is wholly aware of, and working off, the absurdity of this sort of game story; and actually, the story itself is the primary source of amusement. About every character the protagonist meets, Neil has deliciously spiteful things to say, and you continue playing not to complete the idiot quests you're assigned but to get to read Neil's next bit of bile.
In a nice touch, the map displays dotted lines as you move about it, indicating in an annoying way how much backtracking and retracing this kind of game schema requires.
