When I was playing Tabula Rasa (I was twelve myself) there was a kid the same age as me running around with a ridiculously dressed female human character (by ridiculously, I mean "scarcely") and using the "pole dance" emote (EVERYWHERE) released before the game closed down. This was during one of the many raids on an Ashen Desert base with ridiculously powerful NPC's. It was during the 20x EXP token and red armor rush as well, which was probably one of the many factors to why the kid (and I) were even able to access that area because it's for lvl 40+.
I think that says something about the maturity of younger gamers... but I was the same age as him, yet I had a fully stealth armored green spiky haired male powerhouse.
Maturity doesn't depend on age, based on my experiences. It just depends on how you're raised.
The bulk of "annoying" young gamers probably weren't raised right, or they could be so sick of being a goodie two shoes IRL that they want to just unleash their stupidity onto the internet.
Also, as for my last comment about how the kid got into that area, I always think about if kids that are immature would even have the patience to get good and experienced at a game enough to get into high levels. Maybe if they never released 20x EXP tokens, I definitely would've kept playing to max out everything, but it gets me wondering about that other kid.
Maybe maturity and patience go hand in hand. :/ This goes along the lines of what other people were saying about rank systems and such; only play with experienced guys.
Maybe experienced "youngsters" are more mature.
