Foundation is a gridless medieval city-building simulation developed and published by Canadian studio Polymorph Games — a love letter to the golden era of city-builders that combines the deep resource management of the Anno series, the organic settlement growth of The Settlers, the freeform creativity of SimCity and the narrative encounter system of Crusader Kings II into a single, laidback and beautiful medieval package. After spending five years in Early Access from February 2019 onwards, the game reached its full v1.0 release on January 31, 2025, emerging as one of the most polished and content-rich city-builders available on PC.

Key Features: • Gridless organic city-building — settlements grow like actual medieval towns, shaped by terrain and need • Node-based monument builder — design custom Abbeys, Castles, Churches from modular components • Complex production chains — Anno-style resource management woven into village life and trade • Customisable rulesets + Aspirations — relax in Creative mode or pursue specific village build goals
