Only played the Core game so far, but it worked very well. The game itself flowed quickly and the rules were pretty easily explained.
I had no problems with the game, but I will caution buyers that you do need at least two types of tokens, along with some way to indicate first player. These things are not included. It's not hard to go grab tokens, it can be as simple as grabbing a deck of cards and using them.
Overall clarity and printing quality was perfectly fine, no issues there.
