Neuroshima Hex is a rare instance where I would go as far as describing a game as being perfect, but it really is, a perfect two-player, head-to-head, light strategy. The artwork is excellent, the production quality is beautiful and the game is elegantly simple to play but complex to master.
It takes all of 10 minutes to learn how to play the game, and about 15-30 minutes to play it, but the real depth is in the strategy and can vastly playing depending on who you play.
The only thing that stops me giving the game a 5 is that it is suggested for 2-4 players. 2 is perfect, but as you add more players elements of luck take higher precedence in determining the winner.
