I probably wouldn’t want to.
Sony has confirmed to Kotaku that you’ll be able to use your real name on the PSN starting day one with the PS4 launch (and not something to be patched in after launch). Since this is an optional feature, you aren’t required to use your real name and can opt for just your PSN ID to be displayed.
If previous information from PS4 developers stands true, you’ll be able to use your real name or username to send friend requests, choose exactly what you want to put for your first and last name (they don’t have to be your real ones, as Sony has confirmed), and you can display both your real name and PSN ID at the same time, as shown in the header image.
Will you be using your real name? Or some other pseudonym? Let us know in the comments below.
