If your user name appeared to be a real first and last name (fictitious or not), your user name has been changed to just your first name. As of May 1, 2018 no full real names are allowed as user names.
It also depends on the game for me. Like Mortal Kombat 11 where they sell characters as dlc. I love the game. But the DLC characters aren't worth buying because I bought Shao Kahn for 6 dollars and he's a terrible fighter in the game. So I'm glad I didn't invest more in this game.
