Yeah, I know it's odd question, but are there any chances for relase of non-ero installer for Utawarerumono? I don't really mind H-scenes, but I think game would be same good without it (and I could let my brother play it ).
H-scenes are rather important in this game(without some of them the story plot can't continue), not all of them but ... I don't think u will be able to find a non-H installer.
Just play the game and when u're brother is on it , just stay near XD.
