Depends on if people who knew me by my current username (TheGhostlyGoat and sometimes Turtlex) would know me by this new name. I've changed my username A LOT, and I hate that I change it so much but I just end up disliking most of my usernames within time. But if people would know me by a new username, then yes. Actually, even if we were just given the option to change our in-game usernames, I'd probably change it still.
I'd probably change my username to something like WornSkateboard which I've started using occasionally, or possibly a variation of TheGhostlyGoat.I don't know, but yes, I would change my username. I like having something that is unique, recognizable, and relevant to myself as my username, and I tend to make usernames that aren't going to really represent me for too long. I'm even tired of my new username TheGhostlyGoat at this point, but hey, I can't stop myself from changing.
