Welcome @Morkai !
I also use Rocksmith a lot, albeit not Rockmith+. It totally s#cks, compared to Rocksmith 2014, in my opinion!
If you like the gaming mode, have a look here: List of play-along songs with synchronised tabs on Youtube
There is a “trick” to use gamification with about any song you like. I even created a video for “Billie Jean” (it’s the first).
Also, I am an (Dutch) expat in Germany - and we have a few other “real” German bassBuzzers. If you need help/information about Germany. Happy to help.
One advise beforehand:
Oh, and one more idea, before moving: getting gear in Europe is expensive. Maybe buy it in the US? You can always sell it here for a better price!
