Seriously everyone stfu about the gamertag Fish. It was not taken by a microsoft employee stop speculating and spreading lies. The gamertag was jacked by Drift and swapped and soon after was deleted. The original owner got his account back and microsoft asked him if he wanted his gamertag back, if he didn't they would retire his gamertag. He obviously wanted it back so they put it on his account for him. Obviously he's not working for microsoft because he doesn't have watermarks which means he didn't help develop the NXE dashboard, the kinect, or the Xbox.
