hello quick question
if I were to buy the game here and use the key in steam would i be able to play?
currently in Germany and the steam page says its unavailable

I have a report from someone who managed to activate the key and lives in Germany. I'm not 100% sure it worked for them, just a "both worked thx" referring to the game and soundtrack keys. However, I don’t recommend proceeding with this if it’s considered a crime in your country, unless there’s an exception for games acquired via keys.

German Guy here. There is no law against legaly bought games frome "different" sources as long as you´r an Adult (18 years old) and don´t spread it to minors that wouldn´t be able to buy it. It´s just that "erotic" games and "certain symbols" (don´t need to fill in here what kind, do i?) are not allowed in the Steam Store (they don´t have a german goverment approved way of testing that you´r over 18 years old). Only other Problem i see is the "dlc" stuff we don´t have access to the "Store" page and can´t buy dlc´s. :( is there maybe a why that you make them avalibale here? 

So Short Version:

Germans can activatet your games, its legal and have fun. Cya 

Anleitung für Deutsche: Steam öffnen, Reiter Spiele, Ein Produkt bei Steam aktivieren, Key im neuen Fenster eingeben (copy and paste) und ne Taschentuch box bereit halten oder wahlweise socken.
