Legacy Jak; or Diabolical Wanderer?
Jak and Daxter reference, and your fondness for early Nintendo games; or a saints row/Fallout reference.
You can have spaces in your name for a GT by the way, so that opens up a lot of choices.
When I make up names I chuck random words around with syllables and if it sounds good, I type it out - if it looks good, I use it.
Here's one for you, since I notices you like to use "pete" a lot.
Petesca.
Original, uses Pete, rolls off the tongue, doesn't really sound like any other English word that I know of, Google Search uncovers nothing and the chances of it being taken are practically 0%.
But feel free to knock that idea around, you'll be surprised at how awesome you can make some words or names look and sound through that method. Original, snappy and your own online persona. Try the method out for yourself.
The only downside is some people might not read it the way you intended.
