Why it matters
Main Sequence enters early access with its core loop and full progression flow playable from launch, so the one-to-two-year window is about adding content rather than finishing the game.

The early access build covers the core systems and the full game flow, in which elements increase as the player progresses. Players start with a single spaceship and work toward an industrial empire across procedurally generated star systems, designing ships and stations from modular parts and moving factory goods through space station logistics. Hostile NPCs bring combat, and NPC trading is included.
The developer says there is no strict upper limit on multiplayer numbers, though performance currently drops as player count rises. The price is planned to increase at full release, and a demo remains available alongside the paid build.
