Kuiperium: My Favorite Mechanism

About Kuiperium, from BoardGameGeek:

Kuiperium is a two player scifi themed game where you'll take the role of a corporation building a space station along the Kuiper asteroid belt with the goal of mining "Kuiperium". Kuiperium is a newly discovered element and is incredibly valuable. Race against your opponent to gain control of the space station, mine the most kuiperium, and ultimately launch towards new frontiers. In Kuiperium you'll be playing cards into your tableau gaining abilities and rewards but be careful, every card you play has a worker placement location that ONLY your opponent can use. Place workers, gain rewards and climb the discovery track. Push your luck, tableau building, worker placement, take that, resource and hand management. This game has very simple rules but every decision is full of tension and strategy. -description from the designer
