In my humble opinion the term “adventure game” has become too broad these days. I see some sites even try to classify an FPS as an adventure game. To me it is games like the King’s Quest series from Sierra or Zork from Infocom that defines the adventure game genre. Games that require you to really explore your surroundings, solve many puzzles, and quite often interact with dozens of non-player characters in more than just a “pardon me while I shoot you” capacity. Cryptic Keep certainly strives for the feel of the classics, though the distinct lack of NPCs and very little story save snippets at the beginning and the end make it feel more like Myst than a true adventure game. Still, I appreciate that developers are trying to reinvigorate the genre, and it was fun while it lasted.
