For me:

PC - Modding community, games like Mount and Blade, Total War that you won't really get on consoles.

Consoles - Couch gaming, local multiplayer/party gaming, Nintendo.

Seriously? Pretty much everything that is big on consoles was big way before on consoles.

Online gaming, FPSs, WRPGs, streaming, multi tasking, apps, 1080p, 60FPS, digital distribution, indie games. Consoles are copying PCs more and more. Even the bad part like patches, game installation, drivers update (or in consoles case, firmware update).

Anyway, 3DS > "next gen" consoles.

Modding (some mods are much better than original games)
More genres
Keyboard+Mouse
Surround gaming,

Nothing wrong with consoles though, having piece of hardware that you know will be relevant 5 years (or 7-8 in last gen's case) from now is a major plus.

In my humble opinion every "game enthusiast" should have a decent PC. And is not even that expensive. For instance, two years ago I paid less than 100 USD more to buy a notebook with a discrete GPU there was able to reasonably outperform the Xbox360 GPU (and I live in Brazil where every think related to technology is expensive).

About the "elitist" behavior, I think it is because nowadays many people buy consoles to play "PC games" like CoD and its clones, consequently the consoles/PC comparison becomes inevitable. And since Xbone and the PS4 have a more modest hardware when compared to their antecessors (at launch), unfortunately, thinks may get even more bad this gen.

I actually think there is very little chance of that.

There isn't really a way to effectivly monetize a realistic FPS in a free to play enviroment to start with.  TF2 only pulls it off due to it's random cartoon style.

Additionally, LoL's stats are just absurb in general from a "Hardcore users" perspective.

Of it's 32 million active players, 12 million play every day.

LoL is greatly served by being fairly unique, and more or less capturing an entire genre.  Much how like pretty much anyone playing a canon game plays angry birds.

Even F2P it isn't going to take players away from other shooters in the west.

I love my PC games, but I also love my other systems. They all have their pros and cons. The only thing I will say is that PC gaming has spoiled me in the sense that the sales are unprecedented, and do not come close to comparing with sales for console games.

Sales has spoiled all PC gamers. - However we don't save any money though because we just buy a larger volume of games. :P

I still find it hilarious how Console Gamers feel threatened by the PC gamers.
For a long time I watched how Playstation supporters lauded it over Wii and Xbox gamers, but as soon as a PC gamer entered the foray it was no longer relevant to talk about graphics or power, but instead focused on price. (Which the PC is cheaper in the long run.)

apparently their all about graphics but the most popular PC games look average like WoW, Diablo, starcraft, guild wars, minecraft, DOTA, league of legends.
graphics do matter but to get significant improvements over consoles, and a machine that will last for as long as a console generation, youre looking at spending atleast twice the amount if not more which some people think is worth it, but personally I dont.

Agree with you for a change!

Funny fact : People who prefer less powerful consoles use to bring the PC , like to say " dont care, if i want power, i  buy PC " (most of them wont), but deep inside their heart, they would like their favorite console to be the most powerful and they wouldnt bring the PC if that was the case :p
