Are you into fashion IRL? I mean for a lot of people, flaunting their online looks is important, it pleases them - and they see others rocking a unique skin and appreciate that as well.

I mean I play FFXIV casually, but there's a huge subculture in that game for making looks, combinations and colorings of its huge library of clothing items.

All I'm saying is, withhold your judgment a bit on things you're not into yourself.

Online multiplayer games are how kids socialise online these days. They don't meet up on Facebook, they meet up on Fortnite or Minecraft. Appearance is an important status indicator.

At least Minecraft doesn't charge you to change your skin.

People play these games with their friends online. They also stream to potentially millions of people.

Their online persona is part of their identity. For some people, buying an expensive in game item makes them feel rich/successful/whatever, and some people will complement/judge them on their taste/expenditure etc.

It’s no different to buying a Rolex, a fast car or Louis vuitton hand bag. All of them are functionally the same but convey something about the owner

When it’s an online game played with friends, many will want their character to look cool/unique just as much as they want items/equipment that may give a competitive advantage
