Well, because I already have the Japanese version of the Hoshido path and Invisible Kingdom/Revelations and I have played them on Normal/Casual and Hard/Casual I'll probably play the English version of Birthright on Hard/Classic and/or Lunatic/Casual, Revelations on Hard/Classic and/or Lunatic/Casual and Conquest on Hard/Casual and/or Normal/Classic.
(And I might try Birthright on Lunatic/Classic... I'm so doomed x'D)
