THE WORST GAME ON STEAM

Summary
Mark sets out to find the lowest rated game on Steam, under the conditions that it's a functioning premium title and that it was never intended to be a poorly received joke game. Some of the video games Mark came across include Drug Wars, originally titled Merchants of Brooklyn, and Tunnel Rats. Ultimately, Mark settled on Skyscraper Simulator, which, at the time, had a 6% approval rating from a total of 193 user-submitted reviews, earning it the "Very Negative" Steam ratings tag.
