Yeah, same was true of me until a couple of years ago when I started playing call of duty with my younger brother to reconnect. At least for me, PC gaming puts me in a massive filter bubble in terms of what you see and hear about, and call of duty, which overwhelmingly sells to consoles, has always been viewed sort of derogatorily.

I think on the flip side, most of my brother's friends I played Call of Duty with probably haven't heard of counterstrike, or Quake, or unreal tournament.
