No? I mean, it's not like there aren't already small, cheap PC:s or that they are difficult to use?
There are obvious advantages to both dedicated gaming consoles and PC:s, and to me it's just so much more appealing to play on consoles. Of course there's lots of people with the opposite opinion! But there are many, many others like me.
I get much more of a "gaming feeling" with a console. To me, a PC is first and foremost a work tool. I don't want to feel like I'm at work when I'm playing a game. I've been using both PC:s and consoles since the late 80's, I've built lots of computers and played a lot on them too. Still do sometimes, for the record.
As soon as you need to boot up and use Windows and use a mouse + keyboard, you've lost me. It's not as fun, convenient or appealing. Or when you need to fiddle around with settings, update drivers, download different downloaders to download and play games (...) + there's no physical media which is really important to me. I'm a collector + I want to be able to sell games I don't like or that I am tired of.
Plus the exclusives.
It's not like people don't understand that a PC gives you a ton more options! Mod support, upgradeable parts, plus you can use the computer for a million other things besides playing games.. but that's part of the problem to me. It detracts from the "feeling", from the complete gaming experience.
I bought GTA V on PC a couple of days ago. First, I had to download Rockstar Launcher, get an account, log in then download the game. Then when I booted it up, Windows Defender blocked the game from starting, so I had to fix some settings and make an exception for the .exe file. Then, when I finally got into the game, the resolution was set to 800x600. So I played around with the settings for maybe 15 minutes to optimize..
After that, I really didn't feel like playing anymore. Totally lost any inclination to play.
Sure, it's not always like that! When I play Skyrim through Steam, I just fire it up, no problem. But still, there's almost always something... some shit that just makes PC gaming less appealing than just popping in the disc and start playing. Oh, and being able to put the console in sleep mode and start the game right up in a couple of seconds is just too much of an advantage.
And even if there are small, cheap PC:s, you really can't buy one that is as small, cheap, quiet, looks as nice in your living room, is as powerful (relative to the price) as the PS4 pro with games as good looking as the Sony exclusives. Or the X1X for that matter. Especially not if you include a controller and Windows. At least not easily or conveniently. No, you can't.
So, why would PC:s "replace" consoles? It's obvious that there are plenty of people that prefer both options.
