Stardew Valley has sold more than 1 million copies already, and it’s a game made by one man. It’s also very good, as I noted briefly here.

I think the success of such a game is important for the industry overall, not just to show that catering extremely well to a niche audience doesn’t mean you stay niche in sales, but also because in this day and age, a small (or one-man) team can accomplish great things easily on par with what we consider AAA releases.
