I would be very opposed to any sale of in-game items that exists outside of the Oort economy.
What would be the point of creating a game that has the ability to run it’s own economy, encourage interactions through trading etc if you can bypass it all if you want to throw a bit of real money at it?
There are ways to maintain funding for a game that don’t involve selling anything in game. I agree with Havok that any real money items should not affect gameplay.
