Good chance if your game didn’t do well on Steam that you didn’t make a good game that has high product-market fit in the first place and didn’t promote it properly. We are now in an era where indie devs have become millionaires from their $15 games. And I’m not just talking about Edmund McMillen and Johnathan Blow. Go back to the days of brick and mortar retail and that was nigh impossible when a small studio would earn pennies on the dollar for every sold unit.
