This was my intro to Pathfinder in preparation for a PF Society game later in the week. I found the intro to combat useful along with the circumstances to make a saving throw helpful.
I feel replayability is limited to only a few times once you have the story down it just becomes a combat throw exercise.
The solo includes two pregenerated characters at level 1 and 3 but the intro text doesn't introduce them or how to incorporate them or use them later. (Maybe I'm just too new to PF to figure that out).
For the price I highly recommend it as a learning tool or when you have an urge to throw some dice.
Do note this PDF is not gray scale printer friendly. The PDF has a background that does not print well with the font. If you must print it choose color output.
