One of the games that stood out most at PAX Unplugged 2017 was Eschaton from Archon Games. Their booth had a dark, brooding feel and only contained Eschaton, a game that matched the booth presenting it.
There’s very little color to Eschaton, the game containing mostly shades of grey and black with a few accent colors on only a handful of cards. The most color you’ll find are the colored player cubes which represent influence on the board.
Eschaton is certainly eye-catching!
