It never ceases to amaze me the levels of immaturity and rudeness of a large percentage of the Evony players. Perhaps it is because it is a free to play game that it draws these types to it? I would just like to say that the best players that I have had contact with have usually been mature and thoughtful. That is not to say that they cannot be ruthless if the situation requires it but they usually realise that it is just a game and none of it is personal.
So between mature players, polite conversations can be held even while attacking each other. It is usually only players of a lesser standard that have to resort to trash talking and bashing other players in world chat, mainly because they lack the skills to win on the battlefield.
Unfortunately any player with any common decency or sense stays away from world chat because they recognise it as the un-moderated cesspit that it is. What I really don't like is the current trend to bring the trash-talk into the forums. I would hope that the moderators would take a dim view of it as well and start to clamp down on it soon.
