What was the best-selling home video game from the 1980s?

The answer is: Super Mario Bros. Hey, I had an Atari 2600. I even had a Commodore 64. But let's get serious: Home video games didn't matter until the Nintendo Entertainment System (NES) hit the market.And alongside the NES was the best-selling home video game of the '80s — no big surprise here that Super Mario Bros. takes that crown, selling over 40 million copies in the 1980s alone. Although, it's maybe a little surprising that the first one in the series held strong, even after Super Mario Bros. 3 kind of changed my life.In fact, five of the top 10 best-selling home video games of the '80s were Mario games (assuming you count Donkey Kong, which you better).Source
