Harry Potter and the Half-Blood Prince is a functional game that does the basic job of recreating a highlights package of the occurrences in the novel and film. Even at a slightly lower than usual price, the game really doesn't have enough to justify anything other than a rent. The retelling of the story is poor, the streamlining of gameplay and recycling of the content comes off as a lazy cash-grab, and that's despite having more than a year (possibly two) of development time. There have been worse movie tie-ins made, but few have been functional yet so desperate for attention. Even avid fans of the game will likely be disappointed with this half-arsed effort.
