Microsoft made a second system for gamertags where a player can have the same name than another player but after their name, there is a "#xxxx" where "xxxx" are random numbers.
I changed my gamertag thinking that Sea of Thieves support that system, but no. So now, I have ugly numbers after my name (BlackJames8121).
I see lot of people with that type of gamertag and it can be very cool if our real pseudo is displayed.
