The Cold Commands

Take any of the many non-descript RPGs of the last 20 years (the games variety, not the tank-busting kind), read its forgettable storyline and there you have it. There's Morgan's Cold Commands - if you add slugginess, endless meandering with no real aim and characters with no goals.
Unfortunately, what makes a game good (not very good) is by far not enough to make a book good, since a game has much more than its storyline, while for the novel that is all of it.
