Mount & Blade II: Bannerlord

Mount & Blade II: Bannerlord sieged StreamerHouse in 2020, drawing 398 peak viewers for TaleWorlds' medieval warfare sandbox that became Steam's biggest launch of the year. Early Access hit March 30th with nearly 250,000 concurrent players in the first hours, shattering records as sales reached 2-5 million copies within three days. StreamerHouse sessions captured the community-driven hype—after years of development via the World of Mass Development portal, 85,000 backers finally got their hands on the sandbox they'd shaped since 2011. The game maintained 200,000+ concurrent players while Steam Spy tracked sales eclipsing even Doom Eternal's PC launch. Critics praised the blend of strategy, RPG progression, and real-time battles, with TaleWorlds offering 10% off for two weeks plus an additional 10% for owners of previous Mount & Blade titles. By 2025, lifetime sales surpassed 5 million units (excluding Game Pass and PS Plus), cementing Bannerlord's status as a generational strategy hit. For StreamerHouse, it demonstrated how patient development and community involvement could create launch-day phenomena.
