Space Engineers 2
An engineering sandbox in the Almagest system: your colony ship arrives damaged, so you mine, build and fly your way to a foothold. Design ships and bases on a unified grid, blow holes in everything, and fight NPCs who use your own corridors against you. Still an alpha, and it shows, but the building is already excellent.
