The game works in the stime, as it is written does not show the guide, discussing even what you are playing but it’s the same wolfenstein 2009!

I doubted because the games are not in the Steam store, but the key really worked)

The game has been added, successfully jumped and launched, cool!

While I was doubtful at first (because GGSEL wasn't the first key-selling page I heard about), I can confirm the Driver 5 key I got from Retrovault worked fine. Like the seller said beforehand, the game appears like a demo in one's Steam library, but, once the games is opened, it's the full game. In case anyone is in doubt about this subject, I can confirm the first gameplay segment I got with this key starts is driving to the bridge (<span>https://youtu.be/ZtK5Z7cgjVk?t=232</span>) instead of in inner streets (<span>https://youtu.be/NImLgVdcNzs?t=181</span>).
So, in short, I recommend this seller!

The code got and activated everything well
