Being Andrew Plotkin probably makes a good deal more sense if you've watched Being John Malkovich; so if you haven't seen it, you may well enjoy the game a lot less than I did. I'd definitely recommend watching the film first, if possible, since a fair bit of the amusement I got from the game came from remembering similar scenes in the film. I don't think playing the game first will make you enjoy the film any less, though; and I don't think it counts as a spoiler to note that it's certainly not a direct transplant from screen to, er, screen — and the ending is quite different.
