You know, in some ways he's correct... Just people aren't looking at this correctly.

PC games, unlike console games, KEEP their community of players for quite awhile. A console shooter, for example, becomes practically a ghost town as soon as "the next big thing" comes around. PC titles, on the other hand, have a more faithful community. The community create new maps, mods, and even upgrade the graphics for the games they love. I mean, look how many dedicated players are still on CS 1.6/CS:S/BF2/BF2141/Quake 3/UT99!

Looking at it in this light, there's a LOT of good games on the PC.
