Here are the games I played that actually came out this year:
Pathfinder Adventure Card Game: Rise of the Runelords - Base Set
Ladies & Gentlemen
Pixel Lincoln: The Deckbuilding Game
BioShock Infinite: The Siege of Columbia
Ghooost!
The Three Little Pigs
Cuba Libre
Gunrunners
Firefly : The Board Game
Guilds of Cadwallon
Police Precinct
Out of those my top three are:
Pathfinder ACG
Ladies and Gentlemen
Cuba Libre
Pathfinder has been fun for me, even though I've only played it solo. I find the character progression a neat twist on deck building.
Ladies and Gentlemen is just a blast. Get's even better with some light role playing. The game may sound sexist (Ladies are shopping for clothes while the Gentlemen are at work making the money) but it really doesn't feel that way while you are playing. The ladies half of the game is so much more interesting and more involved than the Gentlemen's half.
Cuba Libre is an amazing game. Don't let the fact that it's done by a wargame company (GMT) deter from the game. The game feels like a euroized wargame. Instead of piles of chits you have wooden cubes and the actions feel more like a euro area control game. The best part of the game is the asymmetrical sides. Each player has their own victory condition and special actions they only they can perform.
As far as the worst one, I'd say Pixel Lincoln. I love the theme and I think the actions you perform really make it seem like you are playing an 8-bit game, the problem is it's dull as shit. The cards you buy aren't that exciting and they don't really don't work together so you don't get awesome combos like in some other deck builders.
