Nope. You can play the newest games on a three year old PC just fine. Since games are mainly developed for consoles, your PC doesn't have to be super high end, it just has to be better than the consoles. Which is easy. Unless you want to play in 4k or something unnecessary like that.
You can build a decent gaming PC for ~1000€. A PS4 costs ~450€. The PC wins longterm because you spend significantly less on games and you don't need a subscription. I own a couple hundred games but I didn't pay the full price for more than maybe a dozen. Also, the PC games continue to work no matter what and even when there is no support from the devs, the modder scene usually patches the worst bugs.
Longterm consoles will lose their marketshare to PCs again and Microsoft/Sony/Nintendo know that. This is why consoles have been gradually changed to mini PCs. If there is a next generation, they'll run Windows and a keyboard will be part of the periphery.
TL;DR Send me the €1000, because I sure as hell don't have that kind of cash laying around. Which you would be able to guess if you actually read my posts.
Ok, I actually did read, so I'll answer all your points one at a time.
Not buying a PS4 because of lack of interesting games, and as mentioned, PRICE, if €450 is expensive, how the hell do you think I would even consider €1000? What kind of upbringing did you have where that sort of money was frivolous enough that you'd double the cost of something expensive, and call it a better deal?
I don't pay a subscription, and I wont, not ever, I think people who pay a subscription to play games they already paid for are stupid. So invalid arguement.
I didn't pay full price for any of my games, PSN has almost as many sales as Steam.
I already run a keyboard on my PS3 for messages, it's just easier. I've been typing most of my life anyway, I still use a keyboard for many things most people use a mouse for. And the PC-ifying of consoles was the worst decision they made. PS3's amazing processor is what saved an otherwise lackluster hardware setup. I'd still rather the PS3's CPU than the PS4's, I consider that a major step backwards.
We could also go into how I've become increasingly disenchanted with PCs as a whole, especially MS and their junkware OS changes, or how Linux is so undersupported despite being otherwise amazing, but we wont, since you're clearly and firmly indoctrinated by the PC Master Race Cult.
