The 21st annual Interactive Fiction Competition is currently on, through mid-November. Voting is open to the general public; the only prerequisite is that you not be an author, not vote on games that you tested, and submit votes on at least five games. (You emphatically do not have to have played them all! In a year with 55 entrants, it is very unlikely that most judges will get through anywhere near all of them.)
Map is a puzzleless parser game by Ade McT. I played it to three different endings, using a midgame save. Though I wasn’t timing myself, I would estimate that this took a bit over an hour over multiple play sessions.
