Have to watch out for a few keys which can only be redeemed in the US.
Yeah this has been a problem for Cormac.
Is there any way to tell which keys won't work for non US customers? Interested in a couple of things...
No way to tell from the listing. You just have to wait for someone else to bite the bullet and then tell everyone after the fact. Just do some googling for the stuff you're interested in and if you don't find some pissed off buyer you're probably safe.
Got away with just scratches and drakensang. Think I'm reaching the point where I have just about everything I could possibly be interested in that isn't new. God bless dirt cheap pc games.
