Games like SETI: Search for Extraterrestrial Intelligence

01

Frozen Frontier(2024)

★ 7.71–4 playersWeight 3.6

ISO Match

66/100

Frozen Frontier is one of the few picks here that keeps the science-fiction, space-exploration setting, and it backs that up with shared area majority, end-game bonuses, income, solo play, and variable setup. Weight-wise it's a close match — 3.57 against 3.83 — so expect comparable depth. It plays the same 1–4 count, though no consensus best is listed versus the original's sweet spot at three. Where SETI leans on multi-use cards and resource-fueled movement, this one adds worker placement, hand management, open drafting, and a modular board, folding city building and industry into its frontier economy.

Nippon: Zaibatsu(2026)

★ 8.61–4 players60 minWeight 3.6

ISO Match

65/100

Area majority, end-game bonuses, income, variable setup, and a solo mode — Nippon: Zaibatsu covers much of the same structural ground as SETI: Search for Extraterrestrial Intelligence. At 3.58 to the original's 3.83, depth is nearly identical, maybe a hair lighter. It supports the same 1–4 range but sings at four players, where SETI's sweet spot is three. The big shift is how you act: instead of multi-use cards and spending resources to move, you're placing different worker types, drafting openly, and fulfilling contracts in an economic, industrial setting rather than deep space.

Underwater Cities(2018)

★ 8.01–4 players80 minWeight 3.6

ISO Match

62/100

Best at two players rather than three, Underwater Cities is the pick to note if your group runs small. The overlap with SETI: Search for Extraterrestrial Intelligence is narrower here — end-game bonuses, income, and solo play — but both are science-fiction games built around a growing economy. Weight is comparable, 3.59 to 3.83, only slightly less demanding. What you lose is area majority, multi-use cards, and resource-to-move; what you gain is worker placement, hand management, and network and route building beneath the sea, giving it a more heads-down, tableau-focused character than the original's contested board.

Endless Winter: Paleoamericans(2022)

★ 7.61–4 players60 minWeight 3.3

ISO Match

62/100

At 3.33 versus SETI's 3.83, Endless Winter: Paleoamericans is a noticeable step down in weight, yet the overlap is broad: area majority, end-game bonuses, income, multi-use cards, solo play, and variable setup all carry over from the original. Both games hit their stride at three players within a 1–4 range. The theme couldn't be further away — prehistoric territory building instead of the cosmos — and it swaps resource-to-move for deck-and-bag building, tech tracks, set collection, and an auction for turn order, so it feels busier and more modular even as it plays lighter.

09

Barrage(2019)

★ 8.11–4 players90 minWeight 4.1

ISO Match

62/100

The heaviest recommendation on this list, Barrage clocks in at 4.11 against SETI's 3.83 — a real step up in weight. The common ground is structural: end-game bonuses, income, a solo mode, and variable setup all carry over. It handles 1–4 players like the original but is generally considered best at four rather than three. Much else diverges: no area majority or multi-use cards here, but instead worker placement, contracts, network and route building, and ownership across an economic, environmental, industrial theme. The rhythm of building an income engine will still feel familiar.

Bitoku(2021)

★ 7.81–4 players120 minWeight 3.8

ISO Match

61/100

Both games peak at three players, and Bitoku matches SETI: Search for Extraterrestrial Intelligence almost exactly on weight — 3.77 to 3.83, essentially the same depth. Mechanically, the overlap runs through area majority, end-game bonuses, income, and solo play. What changes is the toolkit: instead of multi-use cards, resource-to-move, and variable setup, you get dice workers, deck-bag-and-pool building, hand management, and set collection, wrapped in fantasy and mythology rather than space. If you like the original's positional scoring and steady economic build but want a different table feel, this is a strong sideways move.

12

Troyes(2010)

★ 7.71–4 players90 minWeight 3.4

ISO Match

61/100

Troyes shares a solid chunk of what makes SETI: Search for Extraterrestrial Intelligence tick: area majority, end-game bonuses, income, progressive turn order, variable setup, and a proper solo mode, though the two do diverge in other ways. It's a step lighter, too — 3.37 weight against the original's 3.83 — so expect meaty decisions with slightly fewer rules to hold in your head. Player counts match exactly: both run 1–4 and play best at three. The feel diverges where the seed's multi-use cards and resource-driven movement give way to rolling and placing dice workers of different types, reacting to events, and chasing hidden victory points in a medieval economic setting rather than space exploration.
