About Tynan Sylvester

Tynan Sylvester is a Canadian game designer, the creator of the colony sim RimWorld and founder of Ludeon Studios. He started out building Unreal Tournament levels as a teenager, then spent four years at Irrational Games working on BioShock Infinite before leaving in 2012 to go independent. He also wrote Designing Games, a game-design book published by O'Reilly.

After prototyping several ideas, he settled on RimWorld, a sci-fi colony sim built around an AI 'storyteller' that generates drama for the player's colonists. Its 2013 Kickstarter raised CA$268,132, and the game spent five years in early access with a team of two or three before its 1.0 release in October 2018, when it was Steam's top user-rated game.

RimWorld has sold over four million copies, and estimates in 2020 already put its lifetime revenue well above $100 million. Ludeon has grown to a remote team and released five expansions: Royalty, Ideology, Biotech, Anomaly and Odyssey (2025). RimWorld rarely goes on sale, a deliberate pricing choice Sylvester has long defended.
