Crokinole is so much fun. I wish boards were not so expensive and difficult to keep nice or I think it would be much much more popular. It inspired me to try a whole slew of other tactile/physical "board" games.

Most flicking/dexterity games are pretty abstract: lightly themed, if they're themed at all. And a lot of the ones that are themed, somehow don't get it "right". Flickwars is pretty cool in that it's got a light space battle theme with asymmetric team powers. It also has a neoprene board which, while not being as satisfying as polished wood, makes a surprisingly satisfying flicking surface. There's a modular setup to the game, where players place obstacles on or (because of the neoprene surface) UNDER the board. This meshes nicely with the space theme as you can consider these obstacles as gravitational anomalies. All-in-all, it's a pretty lightweight game, but it's a fun diversion from heavier board games.
