I will just answer the overarching question.
Almost everything that consoles have done, the PC has done much, much earlier. IPX Doom, a decade before consoles ever got online. Making small games and online only, Steam for half a decade before consoles.
Shooters, strategy games, RPGs. All were pioneered on PCs, not to mention those games are almost in every case much better than current games. The term "consolification" meaning the game is shitty should give you an idea just how far ahead PCs are in those game types.
Of course, social functions go without saying. Facebook was on the internet browser, not integrated into any consoles for a damn near decade as well.
Oh yeah, also free, open, unhindered internet without any bullshit.
Basically, there are a lot of areas where the PC leads, and then the consoles kind of bumble and stumble onto many years afterwards. Meanwhile, there are not many things that the PC has adopted from the consoles.
In fact, I will make a prediction right now that will definitely come some time in the future, and if it doesn't console makes are morons. Mods. People will be allowed to make their own mods. Which will also completely fuck with any stupid cash grab DLC developers will try to make since the community can do the simple stupid things itself.
