After years, now being in my 30's I can totally understand how online gaming changed me and my interactions vs people that haven't played online games etc are completely different. I used to have a complete disregard about anything in life, I wouldn't mind saying to someone 'get cancer', which is quite awful. Only now that I grew up and reduced my online presence by a lot, also understood that life is life and games are games, I understand how awful of a thing is to wish cancer to someone or even joke about that. People losing families and friends over that thing and I used to just have it as a word.
I can't blame it on my parents either. They tried their best and they gave me everything they could. If it wasn't for them I would be a total loss I guess. Its just that they couldn't stop me from playing videogames or convert my life into videogames. That thing was like a junk during my teens.
That said online games definitely helped me mature as well, I mean its not all bad, I definitely got some good values out of interacting in online video games, and some bad.
Just wanted to bring my personal experience on the matter and what you commented.
