Munchkin

I love this game. In fact, I seriously considered submitting this game for my favorite game. The sadistic joy gained in harming your "allies" is a big plus to me. Also, planning your strategy properly, in order to win the game (which is a daunting task as how most players would do ANYTHING they could do to prevent you from gaining victory) is also a big part of the entertainment part of this game and the replayability. Also, as the title suggests, the players are strongly encouraged to play Munchkins the munchkin way, which is to try to be everything, fight everything, and have everything. This way of playing is strongly emphasised in the cards such as Super Munchkin and Half-Breed. Long live the Munchkin way of life.

However, no game is perfect, including Munchkins itself. The biggest problem is how the length of the game is directly proportional to how many players there are. Although the game is not too long if there are only 3-4 players, personally I believe beyond 5 the game becomes long (and boring) as the opposing players have more sabotages to prevent a player from winning. There is no real fix to the problem, other than perhaps controlling the number of people playing this game in the first place.
