Not only is my blog five years old now, one of my favorite gamebook publishers is too.
Tin Man Games is celebrating their fifth anniversary by releasing the eighth book in the Orlandes setting, Curse of the Assassin. Their gamebooks are available on both Android and iOS. They have music, illustrations, and handle all of the combat and inventory mechanics, which makes them great for places where you don’t want to break out a pad of paper and a pair of dice. If fantasy isn’t your thing they have a scifi/humor series called Infinite Universe (currently only one book) that I really enjoyed, plus a great Judge Dredd book called Countdown Sector 106.
