Cascadia challenges players to build a North American habitat and populate it with animals, an experience that’s governed by a simple ruleset, while still providing for strategy as deep as the lakes of the Pacific Northwest itself (looking at you Crater Lake!).
Cascadia is all about building a harmonious ecosystem, and this is done in two ways: placing Habitat Tiles, and populating those tiles with Animal Tokens, which both earn you points depending on how and where you place them.
