Steam and online distribution way easier than in the 90's and 20's ?
Other players I play with online are always talking about upgrades and saving up for a complete new system with all the latest hardware.
So I think fortnite and PUBG have definitely driven some growth in Gaming PC sales/hardware sales. Also the popularity of youtubers and streamers are driving kids and teens to ask for gaming PCs too.
Now that PUBG is on Xbox there is a new influx of players who started playing it on console but wanted to move over to the PC version.
Shooters on PC are much better than playing on a console, plus you usually get the features, updates and new maps first. But the feel of playing with a mouse and keyboard is way better on PC. Console ones are fun but I much prefer playing on a PC.
