Revenge of the Plague Lord is an expensive expansion pack (especially now that the full game is only 800 Microsoft points through the Arcade Hits programme), but for fans of the game it's a must-have. The extra achievements are a bonus, but the real value comes in trying out the new classes and relearning the game from a different viewpoint. When you throw in the human dimension of taking each of your characters to the multiplayer arena, you have a package worth downloading.
