Did you even game on a PC pre-Everquest? The late 90s is when PC gaming really slowed down, but up until that point there was really no comparison. Maybe if you compared the libraries of all the 16 bit systems combined to PC over the same time frame it might be close, but no single console had anywhere near the library of the PC until the Playstation and affordable consoles with 3D-accelerated graphics came around. At that point in the late 90s, the graphics you got from a $300 Playstation were comparable, if not better than what you got from a $2000 PC, so it was a no-brainer at that point for developers to start switching over to consoles as their primary gaming focus. You could walk into a Babbage's or Software Etc in the early 90s and the perimeter walls of the entire store would be PC games, with a handful of gondolas in the middle with the console libraries. Yeah, SNES and NES each had 700+ games in their lifetimes, the PC probably saw that many games released every 2 or 3 years. Of course, part of that problem was a flood of mediocre games. You could probably find 10 different poker games, and 50 different "3D pinball" type games at any point. And that's not even counting all the shareware/garageware games that were around, I'm talking only professionally published games.
Here's a list of 5720 DOS games over a period of about 15 years(roughly 2 console generations) from the early 80s to the mid 90s:

The first 200-ish pages have publishers listed, so at least 5000-ish of those(25 per page) aren't shareware/bloatware. Heck, just the year of 1990 is showing over 500 releases.
