I personally have been moving away from all the online/multiplayer/coop stuff this gen and will probably continue to do so in the future. I just want to be absorbed in interesting worlds, without dealing with others. Sure, playing socially has it's place, hell most people seem to prefer it, but I don't get the same sense of escapism or immersion with other people involved. Gaming with others often feels like a chore for me.
This hurts coming from Valve, as they are one of the few companies I felt might have had a shot at being, I dunno, a bit introspective maybe? Probably not the right word but whatever. I just don't want the rest of their games to be about dealing with some jackass sluring me over a microphone.
Just my two cents. I'm sure this statement was misleading on some level, but I will definitely be frustrated if it's not just me and Alyx in Ep. 3.
