GeraltOfRivia_PL: Overall, though, PC gaming is less popular.
Why? What are the reasons behind it?
Is it? Don't be so sure. There is more to many things than just a bit of data, and many make ASS about numbers etc.
GeraltOfRivia_PL: Nowadays, mostly everyone has a PC. Why isn't PC gaming more popular, then? It's far more easy to play the game on the PC you also use for working rather than buy a games dedicated system
You are under a misguided understanding there.
For starters, many people don't have a PC good enough for gaming (or only basic), often just a laptop, and many now have a tablet instead of PC, and that coupled with their phone sees to their needs ... games aside.
Who says, with any credibility, that PC gaming should be more popular.
Most PCs that are work related aren't that good for gaming, certainly not demanding gaming.
The fact is, PCs often have issues due to hardware compatibility etc, so Consoles are a better guarantee for good gaming if you don't want trials and tribulations and frustrations etc. And as has been said, consoles are far less cheaper than a comparative powered PC. And let's not forget about big widescreen TV and great sound systems - sure you could hook up a laptop or other PC to that, but a console is far simpler and often gives far better results.
Overall price also plays a part - hardware plus games. So you can get quite a variance there.
Depending on where you live, buying a console for the kids for Xmas or a birthday has great appeal to parents ... the price of games not so much. And once you get used to something like kids do, consoles just seem far less trouble than a PC for games.
Hell aside from a somewhat brief love affair with N64 back in the day, I remain a PC gamer, but watching my kids play on playstation and xbox devices has often blown me away and made me feel a bit jealous ... never mastered their controllers alas. Watching them play games like Witcher, Skyrim and Red Dead Redemption and Halo etc on our big screen TV where they looked so superb ... and they often connected with other mates online. Easy to see why they neglected the humble PC for gaming most of the time ... that changed a bit when they became adults, where they just expanded where they would play games.
P.S. Any true modern gamer worth their salt would play games on both PC and Console ........ me, I am just a Relic .... like a good number here. And many also play on their tablets and phones too ... they game anywhere and everywhere.
P.S.S. Games come in such variety and prices these days, that it is too hard to be objective about what is more popular. Many around the world would buy a cheap PC and cheap less demanding games. How do you compare them to those with plenty of money to spend on hardware and games. And then there is all those somewhere in-between.
