What about when I did it?

Is it just me, or is TF2 vastly more prevalent and talked about online than CSGO or DOTA 2? I just see far more talk about it in general places and far more videos, community creations, etc created for it even though the the other 2 games have way more players. The game is nearly a decade old and it's fanbase is still pumping out content daily.

And yet Valve is too slow to capitalize on this.
