merow: Hey!
Anybody tried a games for windows live-Key from nuuvem in another region??
Leucius: Not recommended. GfWL from my understanding is very region specific, at least that's my understanding.
Actually, GFWL is less region specific than Steam. If you're in an unsupported region, you could simply make an account setting the country to a supported region. In all the time I used GFWL, I never encountered a single game that couldn't be added to my account. For the record I created an account in Japan but specified it as a UK account.
I could play Red Faction Guerilla on GFWL right from the "international release date", despite those who bought it on Steam having to wait an extra 3 months before Valve would unlock the game in Japan.
That said, I have no experience with GFWL keys purchased from Nuuvem so cannot comment on whether they are selling a specific language version or not.
