--Console: buy a console. 1 wire to the wall, 1 wire to the tv. Charge controller or plug that into any USB socket. Buy game. Download or pop in the disc. Install. Begin playing.
--PC: buy a case, a PSU, a MOBO, compatible RAM, CPU, GPU, SSD. Make sure all 10 internal cables of varying sizes are plugged into each device properly. Make sure you put the paste on the CPU lid properly and carefully screw/latch the heat sink to the CPU without bending anything around it. Go into BIOS and tweak everything so the RAM works right, your CPU is running at the right freq, your drives load in the right order, etc. Format your SSD. Install your OS. Spend 2 hours downloading patches and updates. Spend another hour uninstalling and deactivating Windows spyware. Then install Steam/Bnet/Origin/Epic. Then buy and download your game. Then check all the graphics settings and fiddle with your resolutions and FPS caps. Begin playing.
I mean... Yea. I understand the frustration someone who just wants to play games would have dealing with all that PC shit.
PC gaming is a hobby, not just a time killing extracurricular activity. You got to make it work. Sure you can waste a few hundred more on a pre-built PC - or - you could just buy a console for way less and save your money for more games.
Some people just want to play a damn game right out of the box!
EDIT: also, consoles provide a convenience that does not exist for PC gaming. If the world was PC only, I'd wager pre-builts would take over where consoles are now and PC gaming would be consolidating itself down into a common denominator standard, much like console do, to make game development faster and easier. So, although people look at PC gaming as this utopia of unrestrained gaming potential, the reality is companies would eventually compete with exclusives, walled gardens, and more proprietary devices and accessories to claim marketspace. It would effectively become a console-like market.
