Im pissed off. I finally bought Shogun 2 today, inserted the disc, ceremonially installed it, selected language "English" and with delight in my heart, started it for the first time.
Only to be greeted by a German menu.
Very much miffed, I quit, went into steam - and discovered that the language seems to be fixed for my version. Hooray...
I only hope they did a better job with the translation than in previous titles.
