@Eder I agree with what you said. People have been trading their 18-digit (pre-order) that leads to a 20-digit (early access) codes to each other. I just realized something.

The retail code (game code that they will give out on the 27th, release date), will also be region locked, based on some threads that I have read around the forums.

There will be mass trading again of retail codes IF the 20-digit early access code is not tied to the account.

What's worse is that people who might have traded NA codes that might have been acquired via the Amazon pre-order cancelling trick for EU codes unwillingly acquired from GMG will get into trouble.
