Taken on its own merits, Get Lucky: the Kill Doctor Lucky Card Game is quite amusing. Players take turns trying to kill Doctor Lucky by attaching motive, opportunity and weapon cards to characters, and then manipulating the position of those characters in order to make repeated attempts on the life of poor Doctor Lucky, whose presence in the game is represented by a pawn that moves between the characters. It is up to the other players to foil the murder attempts by spending cards from their hands, which are valuable and finite resources.
The cards are peppered with the usual great graphic design and biting humor that we've come to expect from James Ernest's Cheapass Games, and they are further enhanced by a series of word puzzles that have no direct bearing on the game, but give players something to talk and think about while playing, which enhances the 1920s drawing room flavor of the game.
The game does a good job of being a card game version of Kill Doctor Lucky -- perhaps too good. The game play, flavor and overall experience of playing both games is so similar that I can see little reason to choose one over the other, and I can't even say which is the better game. When looking at both games, Get Lucky doesn't really seem like its own game so much as it feels like a variant of Kill Doctor Lucky where you play without the board.
Rating: 3 (out of 5) if you don't already have Kill Doctor Lucky, 2 (out of 5) if you do, or if you just prefer board games to card games for whatever reason. They really are so similar that I don't see much point in having both games.
