There are regional restrictions for this game, not everyone will be able to activate your key...

  and others get this sub, hover for countries where it can be activated
• Japan, Taiwan and some other far east Asia countries get an Epic games store key. (Thanks pivotalHarry)
• Middle East gets this sub, hover for countries where it can be activated

I assume that you are concerned by the last case (other regions) and that your key will probably not be usable in these countries:

In my opinion, it would be better to delete this giveaway, and then recreate it properly with the correct restrictions. That way, you can avoid the hassle caused by a winner who can't activate the key — but feel free to deal with it the way you prefer. :)

Good luck everyone!
