Terraforming Mars is One of The Best Games of 2016

Terraforming Mars, despite its intimidating name, is a clever, ambitious strategy game that manages to give players a lot of options and decision points without leaning on too many rules. Games run long, but there’s minimal down time and a lot of ‘doing’ for players, and the only real lag is the end-of-round accounting that can slow the game’s progress.
Based on the abysmal trilogy of novels by Kim Stanley Robinson that begins with Red Mars—a dry, plotless slog where a bunch of one-dimensional characters form the first human mission to colonize our planetary neighbor—Terraforming Mars pits players as competing companies, working to gradually remake that planet, raising its oxygen level and temperature while developing water sources. The board divides the surface of Mars into a hundred hexes on which players can place ocean tiles, greenery tiles, city tiles, or other special features to generate points and try to raise any of those three core variables (oxygen, temp, water) to advance towards end game.
Within that theme, though, Terraforming Mars is essentially a game of resources and buildings. Players collect income (one resource) and generate five other resources, steel, titanium, plants, energy, and heat, that they can use to play hand cards representing buildings or events, or to directly raise any of those three core variables. Cash rules everything around Mars, so players can directly buy buildings or certain tile types, but it’s easier as the game progresses to improve your resource generation so you can play those cards without money—building certain cards with one steel unit replacing two coins, or using eight plant resources to place a greenery card.
