If I buy an xbox one to play ESO and use my Microsoft account (which has never been used on an Xbox) or my old xbox live account from 360 days (which has a gamer tag I do not want to use) will I be able to change the in-game handle/gamertag to my liking? I do not wish to create yet another Microsoft account and have to register yet another e-mail address to keep track of.
Since learning I must use my inappropriate PSN handle created over a decade ago in-game on PS4 version I no longer wish to play ESO on PS4 (nor do I intend to buy any playstation products again until Sony reverses their no-name-change policy is reversed).
