The original Pillars game is one of my favorites. I like it right up there with Stone Age, Dominion, and Puerto Rico, and this expansion really adds to the game play.
Here is why I like it:
1. Most importantly it takes it from a 4 player game to a 5-6 player game; this is huge because too often we have more than 4 and are pigeon-holed into the games we can play.
2. The expansion really adds some great cards and master builder placement spots to the game, balancing it a bit more. It makes getting the gold-for-wood card, or the free resource cards not quite as powerful, and opens up the strategy.
3. It just adds more intrigue to an already great game.
Have Fun!!
