I don't really consider Choice of Games to be choose your own adventure. Their stories are entirely linear, and your choices don't affect the course of the game at all. They only affect the immediate dialogue, and most of the choices are just right or wrong. I also find the plot to be quite shallow, and if you want to make any "exciting" choices (which are just little side stories that do nothing to advance the plot) you have to sell your firstborn.
Edit: Nevermind. Was thinking of wrong company.
