Can someone explain me what's the use of avatars? As I can see most of the players haven't changed their avatar since the first time they joined the game. Others change their avatar accordingly to the ongoing event to show off they already have beaten some stage or finished the event. And at the end there's just bunch of them in the last era. 9 of them are waiting for you to research. Is that a lack of imagination or just you (developers) have some weird sense of humor?
