Thanks a lot for answering!
I wasn't aware Steam users could still activate codes for restricted games in Germany. If that's the case, it should be fine at least for the Kickstarter backers!
Just one more question: from what I understood, the gameplay part of the game is mostly safe for work/showcase e.g. at local tourneys and the explicit scenes are only presented in story mode. Is that correct?
In any case, good luck with the Kickstarter launch! I am honestly very curious to try the game out!
