I just played a game I liked very much. It is a Source mod called The Stanley Parable, and is free for anyone who owns a Source game on their PC (and at this point, I can’t imagine why you wouldn’t, but if you’re one of those weirdos than you’ll be happy to know that Valve is releasing the Source SDK for free sometime soon.)
Normally I would do a Close Look, but instead I will just say Play The Game, because it is better if you know nothing. Don’t even read the description on the download page. Hit download, install, play. Any post-game analysis I have to offer would be superfluous: it is not a subtle work, and you don’t need to be a game design expert to get what it’s doing with its experimental first-person narrative. Basically, it’s the best game in that little sub-genre since Dear Esther, with a healthy dose of Pushing Daisies thrown in, and its short enough that there is absolutely no reason you shouldn’t check it out.
Oh, and you should play Dear Esther if you haven’t already – I wrote a chapter of my pending-publication book on it, and will return to covering it when the remake comes out.
