I was about to write a review....

...for the delightful new jewel-collecting (engine-building) game Splendor.  However, after 5 games this past Saturday won by the same damn player using the same damn strategy, I'm concerned.  I fear that this game has a dominant strategy that doesn't even involve ever doing one of the 4 possible actions available each turn (the holding).

I need to play a couple more times to confirm but my review may be disappointing.  Sigh.
