We tried two games of IceTowers using the pieces that would be in three Rainbow TreeHouse sets (3 each x 3 colors x 3 sizes). If I may quantify a subjective value, I'd say the excitement of the game was directly proportional to the number of pyramids. i.e. IceTowers where each player has only 3 pieces of each size was only about 60% the fun of regular IceTowers. Since I've played a game or two of "full sized" IceTowers, these abbreviated gamed seemed to be over just when I thought they should be getting juicy. However, with fewer pieces and therefore fewer towers, I found it easier to consider all my possible moves in the endgame, as opposed to being overwelmed by the possibilities. In this sense, it's a pretty good intro to IceTowers. But the important thing is _it_worked_. I think FOUR people, each bringing a TreeHouse set to the table, could play a pretty darn satisfying game of 80% IceTowers. Ryan
