Love him or hate him, PewDiePie is influential in the video game industry. You Tube videos are some of the best advertising.

Whole bunch of prominent YouTube content creators are huge for the industry on all levels.

This is why you see a whole bunch of them gain early access to certain things. Its essentially free advertising to a huge market of people. If Pewds has fun playing it or something crazy happens then it WILL make people want to play the game, preorder it or whatever.

I myself first wanted Hotline Miami after watching Sips play it, for example.
