I was introduced to Killer Bunnies this weekend and had a blast!
http://en.wikipedia.org/wiki/Killer_bunnies
The primary object of Killer Bunnies is to acquire carrot cards, one of which is revealed to be the winning "magic carrot" at the end of the game. This is done primarily through the use of bunnies, which allow the use of many in-game actions. Thus, the game revolves around playing bunnies and eliminating opposing bunnies through various means (some comical and some violent, but the game art never shows blood or gore).
Each player maintains a hand of five cards and a run cycle of two cards. In each turn, players may play one card. They are given the opportunity to purchase Cards from the market, use very special cards that are in their hand, or target weapons or cards at another player. Then the player's hand is replenished, and the player flips over the top card (which is a Run card) so that the card is face up and visible to all players. Then the player slides a face-down card up to where all the new cards are revealed. Then, the player draws a card to replenish their hand to five cards, and places a card face down on the playing surface.
Cards may be one of different varieties: "Run" cards are the basic type of cards, while "Special" cards are those that may be either played normally, or may be saved for later use when put through the run cycle. "Very Special" cards are similar, except that the player may choose to play the card out of turn, immediately from their hand. There are also the "Play Immediately" cards, which are played whenever they are drawn. Finally, "Kaballa Dolla" cards represent the monetary currency in the game, which may be used to purchase various items at the start of the player's turn.
The game continues until every Carrot card has been acquired by the players. At the end of the game, a stack of smaller carrot cards, each of which corresponds to a large Carrot card, is turned over one card at a time. The last carrot card drawn is the Magic Carrot, and its owner is named the winner. A player, however, requires a bunny in play in order to win the game - if a player is without bunnies at this phase, their Carrot cards are given to other players.
