If it hasn’t been hijacked yet, PSN is finally going to allow you to change your username. Sid Shuman says it’ll be free the first time, and $10 or $5 (for PlayStation Plus subscribers) after that, and the feature has some odd limitations:
When you change your online ID, you will have the option to display your previous ID with your new ID, so your friends can recognize you. Once you decide to display your old ID or not, you won’t be able to adjust this after completing the online ID change process.
The name-changing feature will be in a temporary “preview program” in November for people who have registered to test pre-release versions of the PlayStation 4 system software, and it may break some recent games:
This feature is compatible with PS4 games originally published after April 1, 2018, and a large majority of the most-played PS4 games that were released before this date. However, please note not all games and applications for PS4, PS3 and PS Vita systems are guaranteed to support the online ID change, and users may occasionally encounter issues or errors in certain games. If for any reason you experience issues after changing your ID, you can revert back to your original ID for free at any time (you will only be able to revert once during the preview program). Reverting back to an old ID will resolve most issues caused by the ID change. In addition, when this feature officially launches, a list of compatible games published before April 1, 2018, will be provided on PlayStation.com for reference before you make a change.
It sounds like some games may just be broken for anyone who wants to play them after changing their name. I hope that Sony has a better workaround than “pay us to change back so you can play old games” before the name-changing feature ships to everyone early next year.
