Link UK & US Version?

I can't seem to find the answer to this so I need to ask. Is it possible to link your account with games from two different regions? For example I would like to buy/add the key from a UK version of Nightfall to my US version of Factions; possible?

As far as I know, accounts can't be linked if the key already has been used to create an account, no matter what version.

If you however have an US Nightfall account, bought a UK Factions key and added the key to the Nightfall account...that's perfectly possible.

I would think that they would both have to been registered in the same region , ie a UK and US account both registered in US , the game is no different in different regions .

Edit - Arduin put it far better than me

Yes it is possiable.

No, I haven't purchased them yet so the keys have not been used. I was going to install the US Factions and then link the UK Nightfall to it. Just wanted to make sure it would work before wasting money.

Okay, so no, that would be no problem.
