I know one game notorious for this, Diablo 2. There is nothing more annoying then lag that costs you a win or makes you dead for no good reason. Diablo 2 was just downright embarrasing: "(Insert character name here) was slain by the most pathetic creature in the game" ONLY because the internet cut or the game lagged or something else. Of course everyone laughs at you for your epic fail.
So Escapists, tell us you lagging troubles
Assuming you are now lag free now with your fibre optic broadband and 50mb per second and such
