The World of Warcraft Retro Launcher recreates the look of old WoW launcher through the ages, from a simplier time before the battle.net launcher, AND takes the creative liberty to update its looks for newer expansions as well. The launcher works will any and all WoW versions - retail, classic, even PTR. And yes, this launcher does of course come with the iconic sound that used to play when the massive PLAY button was clicked.

The only catch is that you do unfortunately have to write your password in the log-in screen,
BUT!! if you remember to click "Save this account" at the log-in screen, you will not have to keep writing your authenticator code over and over.
