The game is the same. The only difference is that the electronic version (e.g.: Steam) is only on your PC and you have to download it when it comes out. The retail version is in the classical “box” with the CD. It says german because the box and everything inside is in German, but the game can be played in English as well 😉
So, in order to choose: if you really want the box or have a veery slow internet connection, go for the retail version. Otherwise the electronic one should do just fine
