You know one thing I really wish the world would translate better from online to off?
Nicknames.
What do you care if someone's name is KT or Coles or Alex or KingYolo. Sure, some of them can be silly - but trust me. I have known people with legal names far stranger than Giga or Ghost or ButterGod62.
We have serial numbers - why can't they just be linked to whatever we want to be called?
