" Classic core gamers  the ones that play most major hits or jump from indie game to indie game  are relatively rare when compared to overall gaming audience.
In fact, 1% of Steam gamers own 33% of all copies of games on Steam. 20% of Steam gamers own 88% of games. Thats even more than Pareto principle suggests.
So, to be a member of the 1% group of Steam gamers you have to own 107 games or more. Thats not much considering how Steam is selling games at discount prices and how easy it is to obtain games in bundles.
Were talking about 1.3M PC gamers that could fall into definition of core gamer that buys several games per year. And thats including discounted games as well.
Of course we could extend it to, I dont know, softcore gamers  the 20% that own 88% games. To be included youd have to own 4 (FOUR) games or more on Steam  not exactly a huge number, right?
Let me repeat it once more, because its really important.
Various studies suggest that there are 700800 million of PC gamers. Its probably true, but it doesnt mean much for your game.
Because if youre developing a downloadable game for Steam youre not even fighting for 135M of its active users,
youre fighting for the attention of 1.3 million gamers
that are actually buying lots of games. "
