Imagine for a moment, an Olympic track event where athletes get deliberately tripped and injured by the opposing team. Or a losing Rose Bowl team yelling physical threats at the other team on national television. These are both examples of poor sportmanship that no one would tolerate.
Yet daily in Cyrodiil we see hate whispers, unsubstantiated accusations of cheating, exploitation of broken sets and mechanics, zone chat harassment and threats, sniping on duels, large zergs running down solo players nowhere near active "war zones" and other behavior that demonstrates that many players show no respect for other players (enemy or ally) and appear to be solely focused on winning regardless of method.
On the other hand, we have pvp guilds that reroll factions to help balance servers to make a better playing experience for all, many players that silently DON'T engage in trollish behavior, and I know I get a lot more "gf" whispers than nasty ones.
What do you believe? Is sportsmanship a valid concept in a videogame war, where the consequences are digital, the teams are neither fixed nor regulated, cultures mix which have differing ways of expressing sportsmanship, and no one gets physically hurt? Is it silent enim leges inter arma? That sportsmanship is as important online as offline? Or somewhere in between? And if you do believe in sportsmanship, do you always succeed in holding yourself to that standard?
