Sports are about the same thing.

Karl Malone - The Mailman
Shaq - Desil
Wade - Flash

Those are just 3 but tons of sports plays have nicknames and are just as well known by them as their real names. Those who closely follow the sport will know their real names but casual people will call them what ever they are called the most.

It isn't quite the same thing in videogames but it isn't big enough to where it can be compared at that kind of level.
