    Gaia Project: The Lost Fleet

    Worth it

    BGG reviewers call it 'not to be missed' for long-time fans and rate it 8.9 vs 8.3 for the base game; one thinks the Bal'taks are probably broken. Suits experienced groups more than newcomers.

    Needs: Needs the Gaia Project base game. It is the only official expansion and is not included in the base box; Capstone sells it alone ($34.00) or in a Gaia Project Bundle with the base game ($74.99).

    Adds: Four new factions, proto planets and asteroids, new sector tiles and maps, four ships that open new actions, new tech and scoring tiles and an updated solo Automa.

    Fixes: Moves Q.I.C. actions onto the ships, so there are more actions to compete for. Includes small faction balance tweaks and ends the Terran and Bal T'ak monopoly on transdimensional planets.

Gaia Project expansions: quick answers

Which Gaia Project expansion should I buy first?

Gaia Project: The Lost Fleet. A BGG reviewer who loves the base game writes that it did not need an expansion and occasional players will find plenty in the base box, but for long-time fans who have played dozens of times it is 'not to be missed' and everything feels refreshed; others in that thread call it 'the best expansion in the series' and say they will 'never play without it now'. A second BGG reviewer who played it at launch says it feels 'so much more open' than base, with more ways to get power, coin and knowledge actions, though he also calls the Bal'taks 'probably broken' in his early games. The expansion rates 8.9 on BGG (about 1.2K ratings) against 8.3 for the base game, and was a 2024 Golden Geek Best Expansion nominee. Since it adds new factions, ships and balance changes to an already heavy game (BGG weight 4.49 vs 4.40), it suits experienced groups more than newcomers.

Is Gaia Project: The Lost Fleet worth it?

Our verdict: worth it. It adds: Four new factions (Darkanians, Mowyed, Space Giants, Tinkeroids) on two new planet types (proto planets and asteroids), new edge 'interspace' and 'deep space' sector tiles with new map layouts, four Lost Fleet ships that open new actions, tech tiles, federation tokens and artifacts, 3 standard and 6 advanced tech tiles, 4 round boosters, 3 round scoring tiles and 3 final scoring tiles, plus an updated solo Automa.
