Here's a strategy tabletop card game using a hex-grid. Game is called Factions! Games take approximately 45-60 minutes per game. I suggest taking a look at the artwork www.facebook.com/theorycraft.
Strategy Card Game
looks serious, although cant help but feel this is something better suited for mobile than a board-game. intending for a future port?
Do you have a Board Game Geek (BGG) entry for these games?
It would seem as if most of your content is superfluous. Perhaps you could provide some more details concerning your game.
Most designers prefer to talk more about their games... Or at least make for a better presentation to the design community.
Are you planning to Kickstart this game? And are you planning to use self-service publication? Where do plan to take this game???
Just curious like to see what plans designers have for their games... :)
There is a game very similar to this named Neuroshima Hex! (I realized now that this forum doesnt use any type of BBcode, lol! Why man?):

You can test it on the VASSAL engine. But it doesnt use cards, it use hexagonal pieces but with very similar function.
