As someone here already said, it’s a love-it or hate-it-game.
It’s a fact that the majority of the players have a very bad attitude, but so does the whole internet have, too. The reason why this problem isn’t as usual in other MMOs like WoW and Regnum is that there is many more players in one spot, the game is free, wich draws many lower aged players to it, and that it has very low system requirements.
The lack of knowledge in english can be explained by the low age of the players combined with the fact that many players are from other countries such as the Netherlands, Scandinavia and China.
Even if the majority of players have a bad attitude, there are many exceptions, not all lower aged players have bad attitudes and spelling. (Take me as an example, I’m 13 and live in Finland.)
