KOEI does give pretty good GBA support (Although most companies do), so they most likely aren't "anti nintendo" they probably figure that the targeted demographic for the majority of the games they make (such as ROTTK, PTO, NA) are not represented on the Gamecube (I could say how they are wrong and all, but they probably know best, unless they are mismanaged and jaded). But hey, you never know, maybe we will get some ROTTK game or maybe a Nobunaga's Ambition, anything is possible, as we all know. I would be happy if they made an english version of the Romance Of The Three Kingdoms Advance, but it does not seem likely.
