Boy, that escalated quickly. I mean that really got out of hand fast.
One of the things that got changed around on this game from prototype to final release was the rules about when the game was over. One of the designers of the game has recommended that you play to the end of the list telling you whose turn it is, as the list is not balanced so everyone gets an equal number of turns at all times. Sometimes player 2 gets to have an extra turn for a little while or whatever.
The original idea of the game was to play until the card was finished, not until a player hit 50 points. Playing the card all the way through allows for all players to have an equal chance at winning.
