No Games.

Every time PS4 sales are mentioned I always see "how is da PS4 selling with nogaemz??"

This is why the PS4 is leading in sales and will continue to this whole gen.

Compared to the XB1. the PS4 has the definitive multiplats, the marketing/hype, significantly more games (337 games on PS4 vs 193 on XB1), significantly more exclusives/console exclusives(PC/PS4 only), isn't associated with MS and their bumbling incompetence at the beginning of the gen, and PS4 has three generations of the best library behind it, so consumer trust and loyalty is very strong.

Wii U is just absolutely dead because it has almost ZERO third party support or mature games (not talking about ESRB rating). Only thing it has going for it is a couple of niche Mario exclusives that appeals to people that grew up on the NES/SNES who have never matured and grown up mentally/emotionally. The big tablet controller, s*** online service with most games lacking voice chat and online play at all, and the poverty graphics are just the piss icing on the s*** cake.

PC is irrelevant to majority of gamers; it is overly expensive, difficult to get into (requires ordering parts, constructing it, troubleshooting issues with games), and most importantly has even less worthwhile exclusives than the next gen consoles. PC gaming hasn't been decent since around 2008 or so (coincidentally right around the time of the rise of the "PC Master race!" meme spouters). The only worthwhile PC exclusives in the last few years that aren't already on console or being ported (such as Crypt of the Necrodancer, DayZ, Vanishing of Ethan Carter, Kerbal Space Program, etc.) are PoE and Cities Skylines. 

I don't know how you all can't understand this. It's really just common sense when you look at the facts.
