Does anyone have experience with Nuuvem?

I'd recommend you to read this, although this isn't entirely their fault. Apart from this they seem decent, and the site works well when translated.

very reliable, bought a few times from em. after you bought a game you can access your key by logging into your nuuvem account and checking the games you bought.
can´t remember if you will get aa emial with key as well because my last purchase was quite a while ago.

Site is an official Brazilian retailer, so you can buy there, if game is region locked it will say, about what posted "Number4450" it happens very rarely and only if game has different App ID for different regions, but this cases are practically unique.

Bought from there one game and one addon half price, and no other problem than language. had to use google translate

I think I will take the risk then, the Wasteland 2 is €21, while on Steam it is €40. Even with the 20% coupon I have for GG Nuuvem still a LOT cheaper.
The Game would still be in English I assume?

The key from my Endless Space giveaway a while ago was from Nuuvem and my XCOM:Enemy Unknown key is too. I payed both with paypal and had no problems at all. When you are logged in you can go to your accountpage (top right). There are all your games listed and when you click on one of them the steamkey (make sure the game you want to buy provides a steamkey; mentioned in the gamedescription on the left) is shown on the right next to the gamepicture.

ok, bought the game, key was available installing now
