The 11th Annual Interactive Fiction competition. The games were released on October the 1st, and judging lasts until mid november. All the games are free to play and are designed to take up no more than an hour or so of your time. Indeed if you are judging they insist you stop at 2 hours if you still haven’t finished!
There is usually something innovative or impressive in there, and previous winners and runners-up count among my favourite games in this genre.
