Star Realms

Somewhere in Mind Games, there is a tiny cardboard box with a spaceship on the cover. Inside this box is one of the tidiest deckbuilding experiences you can have.
If you've never had the chance to play a deckbuilder style game, the play centers around drafting the perfect set of cards. In the early game you'll be playing cards mainly to buy hot new cards - the cool part about Star Realms being that you're using space ships to buy meaner and faster space ships - and as the game goes on you'll be using those cards (spaceships) to deal damage (shooting other spaceships) that your opponent controls.
And if you have played a deckbuilder before and are wondering why you should play Star Realms, to you I would describe the simplicity of it. The real draw of this game. Games like Clank! or Cubitos can be more involved and complex but they almost suffer for it when compared the tightness of a game of Star Realms. You're not spending the entire time racking your brain on how to sneak your way to victory and get points for being clever.
You buy a card, and then you use it to shoot the other player. It's genius.

And because of this you can play it with any age group, provided they have some basic reading comprehension under their belt. I gifted it to my fifty year old father and eight year old brother and they annhiliated me the next time I got to play with them.
In praise of the Sci-Fi elements, it is a very realised world you enter and battle in, achieving this through the art of the cards. Every card will belong to one of four factions, each of these visually distinctive with its own style of ship technology. For example, the Red faction will mainly be menancing mechanical rockets and drones, while the Green faction will be grotesque flesh like hybrids of alien and star ship.
The way these factions combo off eachother with their distinct abilities is glorious in action, maybe healing half your health with the Blue cards, or drawing your entire deck in one turn because of your Yellow army. This suits the deckbuilder format so well you'll be shocked it's the first time you're seeing the system.
Yeah it's a Sci- Fi game. But it's also a bit of magic. That's why you should play Star Realms.
