For fans of the old Infocom games as well as for newcomers to the genre, the competition is a chance to enjoy some of the best short adventure games available anywhere. And now, this year's entries are finally available for public testing. Visit IFcomp.org to download the games and interpreters for all of your favorite platforms. For the next six weeks, judges will play, score, and review."
