Not sure if this has been posted yet, but you can try out a bunch of other adventure games also made by AGS, the adventure gaming tool, which was used to create 5 Days a Strange. AGS has a pretty active community pumping out free games.
AGS was also used to create various fan remakes of King's Quest, Maniac Mansion and others.
