Andrew Ian Dodge tells a little tale from his experiences reviewing some online games...
There's a type of person who inhabits MMORPGS: the ganker or griefer. These types, who are generally male, use every possible exploit they can to make sure they can bully other players; primarily those of a lower level. Any criticism is met with cries of "whiner" or "go play something else". What these fools don't care about is the fact they ruin the game for others and in many cases kill off the game they are playing. You see they don't care that game companies need players to keep a game going. Like bullies; all that matters is their fun.
Me, I stay away from them. Because there's no reason to pay ten bucks a month to hear others whine.
