To me, the interesting bit here is less about Steam in particular, but about the industry overall.
Fourteenthousand games. That’s insane. Sure, the vast majority is going to be asset flips and shovelware crap, probably a lot of AI generated spam games in there, too. But the sheer amount is still staggering. That’s a fair few games compared to when I started gaming in 1987, playing Squirm on a C16 with a tape drive.
It is, by a significant amount. The switch has the most at over 4k, a bit more than the PS2 (which also had over 4k releases). The PS2 stat is pretty impressive though, cos they were all physical releases.
