Having long played some old CS, there was so much sense of community from connecting to a personal server instance, regularly seeing the same people, familiarize with specific rules to that server, getting to know the admin etc. I’m sure you feel a sense of community from match making, but to say that it cannot exist without matchmaking is just wrong IMO.

And I’m not advertising for one over the other. But I’d be very happy to see the persistence of accessing personal servers for a game.
