About the game
Foundation lets you raise a medieval settlement without snapping anything to a grid, so streets and districts sprawl in loose, lifelike shapes. The pace is gentle and unhurried, leaving room to shape resource chains and design grand monuments piece by piece. Its hands-off, sandbox spirit prizes the look and feel of your town over strict optimization.
Did you know?
It was developed by the Canadian studio Polymorph Games and, after a long Early Access period, received its full release in 2025.

These are not ordinary keys. A gift is usually region-locked and arrives through someone else's account — if the region does not match, the game will not activate. An account means you get someone else's login: the game never becomes yours, and it breaks Steam's rules. A DLC or a bundle is not the base game. That is why none of them count towards the price at the top of the page.
