It's funny because I was watching the guy from CD Projekt Red on the Giant Bomb e3 day 1 wrap up (
video here, the segment I will be referring to is right at the end at the 2h27m mark) and he asked the guys what game they thought was the best at the show, and how they gauge a game's popularity. Gerstmann explained no one really knows and that it's more of a gut feeling.
Later he was like "there should be an E3 for PC games" and implied that Witcher 3 is better than anything at the show but was being overshadowed by lesser console games that are "flashier" due to their menus.
When asked whether CD Projekt Red considers themselves PC developers first and foremost he said yes of course, and implied that consoles are only in the mix due to the pressures of the business.
It really came across like PC master race mentality imo. As good as Witcher 3 looks, the characters don't look as good as the Naughty Dog Uncharted tease (or even Last of Us remastered). And the idea that console games can't be as complex as PC games suggests the guy has not played enough console games (going back in time, games like Ogre Battle or Tactics Ogre were easily as complex as any PC game during that time) and Witcher doesn't seem necessarily that much more complex than something like the Souls games.
That said, I am very interested in the Witcher series now, and I would have bought Witcher 2 on PS3 had they ported it to the PS3 for us console peasants. I am still planning on picking up Witcher 3 (on PS4 or PC). I normally never buy PC games even though I have a capable rig, as I prefer couch gaming and controllers but this may be the first time I go with the PC version.
I wouldn't necessarily say Witcher 3 was my game of show, because there were a lot of "games of show" for me this year and it is one of them. But it is definitely on my radar. The series really grabbed my attention, and Spring 2015 is looking like it will be insane.
