10. Postal 2

Country that banned it: Numerous

Although this series never quite inspired the national moral panic of Grand Theft Auto, Postal 2 made Grand Theft Auto look quaint. This was a game built to generate controversy as evidenced by the game's tagline: "banned in 13 countries". It featured urination, drug use, mutilation while taking shot at every religion and minority group on the planet, and that's just the stuff that we can mention here. Unsurprisingly, the game built a cult following which is still going strong today.
