The big picture

Terraforming Mars looks like a game about Mars. It’s actually a game about income. The player who builds the better economy in the first half of the game almost always has the better second half, because every point you score late is bought with money you set up early.

The engine and the scoreboard

Think of the game as two overlapping phases:

• Early game — build the engine. Money production, useful card discounts, steel and titanium if your cards want them, card draw if you can get it. Points mostly don’t matter yet.
• Late game — spend the engine. Greeneries, cities, temperature, VP cards, milestones and awards. Money mostly doesn’t matter at the end — unspent megacredits are worth nothing.

The most common way to lose is to do these in the wrong order: buying shiny point cards in generation 2 while your opponent quietly builds production, then watching them out-spend you three-to-one from generation 8 on.

Habit one: income before points. In the first third of the game, ask of every card: “does this make me richer?” If it only makes you points, it can usually wait.

Terraforming rating is sneaky

Every step of terraforming (temperature, oxygen, oceans) raises your TR by 1. That’s 1 victory point AND 1 extra megacredit every generation for the rest of the game. Raising TR early is income disguised as points — it’s the one scoring action that also feeds the engine. This is why “boring” moves like asteroid-for-temperature are often quietly excellent.

Habit two: never let your TR sit still for generations. TR raised in generation 3 pays you every generation after. TR raised in the last generation is just a point.

The game ends when the planet is done

The game doesn’t run a fixed number of rounds — it ends when the planet is fully terraformed: all 9 oceans placed AND temperature at +8°C AND oxygen at 14%. All three tracks, not any one. The generation in which the last of the three completes is the final generation — finish it, convert leftover plants to greeneries, then score. That means the clock is a weapon: the player who’s ahead wants the game to end sooner; the player still building wants it to run longer. Strong players watch the three tracks and count how many steps are left the way poker players count outs.

Habit three: know who wants the game to end. If it’s you, push terraforming hard and starve the tracks your opponent needs. If it’s Matthew, slow-play the global parameters and squeeze more generations out of your engine.

What winning actually looks like

A typical winning two-player score has TR doing a lot of the work, plus a handful of greeneries, a milestone or two, an award that was already won before it was funded, and maybe 10-20 points of cards. Nobody wins on card VPs alone, and nobody wins with a beautiful engine that never converted to points. The skill is the turn — the moment mid-game where you stop building and start cashing out. Most of this guide is about earning a good turn and timing it.
