Why do folk waste their lives playing video games in the first place?
You'd be surprised.. I used to play as a kid, Spectrum and stuff. Then mega drive, PC. But it was down time for me as I'd be cycling, studying etc.. It's very big business, called E-Sports now. It sells games, and unlike movies, games are hard to copy, especially if you play on-line. That said, some of the biggest on-line e-sports games come free, but you can pay extra for additional avatar's etc.
With cheating though, you won't get to the top. Those that are good, have to be good without cheating.
My daughter plays League of Ledgends and is actually quite good, and in a sponsored 'clan'. Before I get shot, she actually spends less time gaming than my son, and she is top class, perfect student etc etc. She does get stuff done before she plays a game (think modern dungeons and dragons). She plays on a mid range laptop, nothing flash. But she only plays League and Minecraft.
My son plays all sorts of stuff, mainly simulators, but does a bit of CSGO. He has an expensive rig he has saved up for though, but he also does photo and video editing on it, and is a whizz on making videos - want's to get into computing/media.graphics as a career.
