Well saying only "video games" is wrong, as this is just another addiction in the end. But I can't be the only one to fuck up his life due to internet and games here, right?
The problem with video games and other shit is how it can affect you when you're young. Being addicted at 10 is worse than being addicted when you have already got a job, I wish I had spent some of that time on other skills that wouldn't be so useless.
I spent years playing the same games and didn't even get good, just another average guy. Now I don't even play those games and even those shitty skills I got are useless. I can't even say I had fun as I wanted to be good but never did. If it was gonna be like this, I wish at least I hadn't sacrificed my school grades.
