Percentages are the easiest statistical figure to bullshit. Just like it happens with “Linux desktop is only 4%”. We are then talking about over a hundred million PCs. PC gaming is 15% means that PC gamers are several hundred millions of devices. Sure, it is less than mobile gaming. But less doesn’t mean irrelevant, and much less a rounding error. You don’t call a fifth of the market that expends almost a quarter of the revenue a rounding error.
