All of us had a problem of choosing a good name for PSN. Still can't stop switching accounts? Try this algorithm, maybe it will help you:

1. What's your favourite game ever?
Nah nothing like cod, choose the game where the story shocked you/made you cry/was epic.
Shorten it by half.
Example:

2. Favourite charachter ever?
Like the one you love

Still nothing? Keep going on.

3. Favourite sportsman?
His name + his T-shirt number
Example: Christiano Ronaldo + number 7 -> CR7
This step is more for the clan names, for example HOT_CR7

4. Favorite movie?
Try to shorten it by half.
Example: Inception -> Incp

Still unlucky?

5. Your country + something?(Name?)
Example: RussianWarzone or JohnAmerica or JohnUsa

idk lol

If you like xXzxZxzxXZx stuff try mixing it up with all above

HOPE IT HELPS!
