From GameWatcher: “If you are a fan of old-school RPGs or a fan of The Dark Eye, Book of Heroes should be right up your alley. The mechanics are complex enough to require you to know the rule book, the world is expansive enough to have a few playthroughs, and the scope is small enough to make it manageable. However, if you have no intense interest on old-school game design or the franchise itself, I recommend you stay away the focus on maths instead of heart and soul makes this the kind of niche game that would feel dated 10 years ago, and the end result in modern times ends up being extremely boring.”
