Really shows how out of touch some PC gamers are here...
On the console side, the Wii U has loads of exclusives considered to be the best, unique games of their particular genre Smash Bros, Bayonetta, platformers, etc. The PS4 has the TLoU and will soon have Uncharted 4, which I'm sure people will pour hundreds of hours into.
There's nothing like TLoU on PC or any other console. The game is critically acclaimed, a grand experience, has great multiplayer and is very popular. Therefore if someone desires that game and will spend hundreds of hours on it, it makes sense they buy console for it.
People have actually done the same thing with Destiny since launch and it works out great for them because they play with their friends on Xbox Live/PSN.
Also, it's not like people only use the console for exclusives. There's a lot of convenient features packed into consoles that make it easy for anyone to use.
This is coming from someone who recently completed a gaming rig, which can run older and current games better than PS4 or Xbox One.
