Interactive fiction - that is: games that use pure text for input and output - seems not to be the topic of a snazzy movie.
But against all odds, GET LAMP, a documentary film on the very subject looks to be very interesting indeed. Jason Scott, the director, has previously put together a well-received documentary film on the bulletin board systems communities.
The recently released trailer for GET LAMP is not exactly action-packed, but a neat dissection of the first ever internet community I actually participated, back in the early nineties, when USENET was king of the hill.
