When I play Quake Live (which I think is the greatest game ever released) I get really excited and obsessed with the game, it activates adrenaline, dopamine, all that stuff, and I literally can't stop playing, and it ends up wrecking my sleep.
When I watch streams on Twitch it's a completely different experience, it kinda relaxes me since I'm not playing myself, and is a social experience aswell. It's like watching your favorite sports event, only you can chat with likeminded people at the same time.
Maybe it's an age thing, I dunno, but I tend to go for the more relaxing, social experience nowadays.
Do you think playing videogames could be an obsessive, addictive thing that even induces aggression, while Twitch is the opposite?
