1) Convenience
My PS4 looks like it belongs in the living room next to my TV, it's a stylish machine (especially in the vertical position). I can play on my comfortable couch and I don't need to figure out how to connect a PC to my TV and have long cords running from one room to another. My PC is in my bedroom. Sure, this is a choice thing, but this how I choose to run my kingdom. The PC is for using the internet and that's pretty much it.
2) Reliability
With a console, I can always be sure that it will run all the upcoming games and I won't have to tackle with a myriad of compatibility issues, outdated pieces of hardware and whatnot that comes with the PC landscape. Okay, if you want to nerd out, you can build yourself a monster rig with all the best components and get maximum graphics and performance out of games, but that would require pretty much constantly upgrading things and making sure that parts work together and it just isn't worth the hassle to me. It's also something I don't want to be continuously pouring money into. Games nowadays look pretty enough as they are and the generational console upgrades are enough for me.
3) Exclusives
Can't do without them Sony exclusives. All platforms have exclusives, but through the years it has become apparent to me that Sony makes the ones that I need the most. And they make a good number of them as well. It's very rare that competing platforms have something to offer that I would even consider playing. So rare that it's negligible.

Also, there's the fact that the keyboard/mouse combo is way too complicated for me to be comfortable with, but I didn't want to make a point out of it, because I think I would get used to it if I wanted to. But there's just something about the feel of things, it's not as good if you have to move a character with one hand (making sure your fingers are on the right keys among a thousand other keys) and shoot/whatever with the other so that each hand is on a different controller. Nah.

Exclusives are what tips me over the edge.

Nintendo comes with an unique experience not found on PC. This was true for all consoles until last gen, where the consoles became closer to PC and got a shitload of PC games ported over. Now most bigger games are on both PC and consoles, and since the games themselves are generally cheaper on PC, guess where I buy them if there's one that interests me (last time that happened was with South Park, so it's a rather rare occurence)

Since I mostly play retro and Indie games, PC is more convenient to me most of the time. And no need to have a big rig for those, either. On the other hand, I bought about 25 Indie games for my Wii U and quite a few WiiWare titles for the Wii back in the day, The Switch, when I will finally get one, will also have the added benefit of portability, and also comes with a lot of great Indies, so it's basically the ideal console for me - just the Virtual console is (still) missing.

Consoles are more convenient and Nintendo games.

PC/Mac kicks any consoles ass for FPS and strategy games just because of keyboard and mouse (but I must admit that motion controls/IR-pointer actually makes FPS:s playable on consoles).

And no aim assist does not make FPS on consoles better or bearable, it’s a form of cheating.

Limited DRM restrictions by comparison
I use a Mac, less games for that
Console exclusives
I doubt I'd enjoy using a keyboard instead of a controller
I prefer physical copies of games and most PC games are either downloads from say Steam or single use codes

Oh and the time, effort and money required to build a decent gaming rig. And the frequency with which you'd need to update it. Simplier to stay with consoles.

high quality exclusives.

Physical game >>>>>>>> Digital

Just have to plug in a console, pop in the game and play, instead of having to worry about a ton of configuration, compatibility, etc. Of course, with installs and updates it's becoming less convenient, though.

Nintendo + PC is best combo for me. But recently I've been only playing League of Legends on PC.

Only if you have a crappy PC, otherwise it is

PC:
1. Buy game
2. Download game
3. Play game

Except we are playing games at higher framerates with better visuals and it can be a vastly more immersive experience.
Sorry you feel threatened by that.

The PC offers both options.
I think it's a little silly to assume that all PC gamers build their rigs when they really don't.

With that... Custom builds are a sizable portion as companies like Razer, Corsair etc' derive a large portion of their revenue from such demographics.

Try browsing this forum on a console. *Shudders*
I would rather drink Mercury.

They will all end up on PC eventually anyway, it's only a matter of when not if.

Perspective and all that.
The PC has hundreds of millions of gamers. 10's of millions of PC gamers have rigs far more capable than the consoles.

Pretty much the entire PS1, PS2, PSP library's are on PC.
Vita, PS3 are slowly trickling in.

Something like 90% of the games on the Playstation 4 are available on other platforms.
25% of all Sony Playstation 4 exclusives games are on PC.

Fair enough if PC exclusives are something you don't care for, personal taste and all that, but don't pretend that the Playstation 4 is loaded with so many exclusives you don't know what to do with them, the bulk of it's library is on other platforms, PC included.

The legality of emulation does indeed vary from region to region.
I can legally duplicate and emulate Nintendo games in my country. (Not that I need to.)

And Sony/Nintendo platforms don't have PC exclusives. That's why the word "exclusive" exists to identify such things. :P

There are OEM's that tailor to such a thing... Where the PC plugs straight into the TV, boots straight into Steams big-picture mode and is usable with a gamepad.

Bolded the issue.
And without knowing the hardware, can't really go more indepth as to why.

You serious? o.0
My Xbox One X would refute that extremely quickly. Haha

You can do this with a PC as well.

Really not the case with consoles in 2017.

If you have a sufficiently capable PC, then generally you don't need to check your hardware.
My PC is 6+ years old and still runs everything maxxed.

Put the game in? Did you not get the memo that PC is a digital platform? ;)

Can't say I have had such an occurrence in years. Maybe back when every PC was using Windows XP...

Controls are pretty standardized on the PC these days.

Lol. No.

With the rate of technical advancement these days. PC's can last years as well.
I have a Core 2 Quad rig as a spare machine, that's Xbox 360 era. - It's playing games from 2017. And will play games from 2018 and beyond.

It has only had GPU upgrade once every few years.

PC isn't one form factor you know, they come in all shapes and sizes... Some can even look like a USB flash drive.

*Cough*RROD*Cough*YLOD*Cough*PS1 Disk drive*cough*Original Xbox clock capacitor*cough*

You can build a PC out of server components... With components that have warranty's that outlast entire console generations.

PC doesn't need a monitor either.

Well. If I was in your shoes I would get better friends.  :P

Entirely subjective, but entirely okay.

I honestly can't think of the last console game I got fanatical about... And I own allot of consoles.

Consoles have a ton of DRM restrictions.

I do have a sizable Nintendo/Xbox collection and a few dozen games on various Sony platforms. But I do agree that I actually prefer Physical games.
With that, I don't really have anything against digital either on the PC, Steam has made it a pretty pleasant experience... Which has resulted in me having 600+ games in my library.
