Based on the 38 4X games SteamSpy listed on November 15, 2026. It misses the games that barely sold, so these figures flatter the genre. Games are grouped by the tags players give them, which are applied loosely, so a genre's edges are fuzzy. Copies are SteamSpy estimates from review counts, not exact sales.
