So, the first game I win.

Don't give it to a friend that is not allowed. That user you won it from is breaking the rules. First of all, region locked keys are not allowed and he is regifting.

The creator said this key is region locked. Why did you enter if you knew that you won't play in it?

Failure on all ends

Next time you enter read the creators comment.

Use InCloak trial VPN account...i bet they have servers in any of that listed countries too.

EDIT: I looked, they have New Zealand.
