It used to exist, but not so much anymore. I miss heavily community based FPS multiplayer games. With custom servers and so on. I played Counter-Strike: Source last night, what a breath of fresh air!
Same, I played some Day Of Defeat: Source also a while back. I got onto a server, people were talking about random things and seemed to know each other, there was a sense of community, it felt like a local bar.
It's 3am and I'm chilling and talking with strangers while surfing on CS:S. God, I miss this.
I miss that in newer games. It's all matchmaking, all competitive and in many ways, modern games like this feels "no fun allowed".
