Terraforming Mars: Prelude
Official Description:
Terraforming Mars: Prelude is an expansion to the game Terraforming Mars, focusing on the early stages of the game. As corporations are preparing to make Mars habitable, Prelude introduces new cards that jumpstart the terraforming process and shape the path players will take. At the start of the game, players choose from Prelude cards that provide powerful boosts and unique starting conditions, allowing for greater strategic variety and faster development. The expansion includes 35 Prelude cards, 5 new corporations, and 7 project cards that can be combined with the base game and other expansions. These additions enhance replayability and offer new synergies, making each game unique. Prelude cards are designed to accelerate the early game, giving players a head start and encouraging diverse strategies. Terraforming Mars: Prelude is recommended for players who want to enrich their Terraforming Mars experience with more dynamic openings and increased strategic depth. The expansion integrates seamlessly with the base game and is compatible with all other expansions, providing a fresh layer of decision-making and excitement to the race for making Mars habitable.
Prelude’s tactical impact is immediate: the expansion injects a burst of momentum into Terraforming Mars by letting players select powerful Prelude cards before the first turn. This early boost trims the slow ramp-up that can bog down the base game, letting engines start humming from the outset. In a collection that cycles through over a thousand titles, Prelude is one of the few expansions that’s never left the table—its ability to accelerate play and diversify openings is exactly what keeps veteran groups coming back. The appeal isn’t just speed; it’s the way these cards force players to rethink their first ten turns, making every session feel distinct even for those who know the base game inside out. From a logistics standpoint, Prelude is a non-issue. The expansion is just a slim deck of cards, so it doesn’t add any setup overhead or table sprawl. Integrating it is as simple as shuffling in the new corporations and project cards, then dealing out Prelude cards before the main game begins. With a 15-minute setup and a two-hour playtime, this is a main event game—definitely not a filler, but it won’t eat your whole night either. The physical footprint stays manageable, and the streamlined start means you’re not losing time to early-game inertia. For hosts juggling multiple tables, Prelude is a permanent fixture: it’s the rare expansion that actually reduces downtime. Teaching with Prelude is straightforward. The only adjustment is running a Prelude round before the first generation, resolving those cards, and then proceeding as normal. The learning curve remains light—players are comfortable by the second round, and the extra corporations add variety without extra complexity. Once the game is underway, you can step away to handle other tables; the competitive, indirect interaction keeps everyone focused on their own boards, with just enough tension to keep the room engaged but not bogged down in negotiation or conflict. Prelude is the definition of a quality-of-life upgrade: it makes Terraforming Mars easier to teach, faster to play, and more satisfying for both new and returning players.
