I don't think it's really possible to set an age limit on games like this, not because the game itself, but there's no way to effectively prevent children from lying about their age.

I was 15 when I found Evony and I think that would've been the very base age limit for some of the chats and things I experienced from my first server. In my personal opinion any child under the age of 16 should never be allowed to even see a game such as this let alone play it.

Not only are 90% of them incredibly annoying and mouthy, feeling no need to respect anyone because its the online world. But I think it's unsafe for them to feel like they have to log into Evony every day because it's setting them up for years of being hooked into a pointless game (no offence to Evony hehe). Stupidly I used put this game before my studies and I wish I didn't have to but back when I was 15 and 16 I had used the game as an escape and I got stuck into it. I wouldn't wish that pressure and loneliness on any child or teenager, it's hard to get out of without any support.
