I have something of an affinity for games that are mean and cruel. You know, games where you get that great first ball, and you just KNOW that you are going to be putting in your Grand Champion initials. Two balls later, the game has completely humbled you and smacked you around like the wimp in those old Charles Atlas ads.
My top two: Whirlwind and Iron Man. Both of these games can be so vindictive it's absurd. Love them both though!
I wouldn't want an entire collection of them, but gotta have at least one of these in the game room.
