Back in the day, the majority of Koei's games were on both Genesis and SNES. The general impression that I get is that Koei's games were better on SNES. But is that true for every single game? Some specific information would be greatly appreciated. I am not concerned with their Japan-only games unless there happens to be one that is in English for some reason. Sadly their few Mega CD releases stayed in Japan.
Genghis Khan II
Liberty or Death
P.T.O.: Pacific Theater of Operations
Romance of the Three Kingdoms II (also on Amiga)
Romance of the Three Kingdoms III
Uncharted Waters: New Horizons
* I'm not sure what's up with Nobunaga's Ambition. Wikipedia seems to imply that the US releases by that name for Genesis and SNES are two different games in the series in Japan. GameFAQs and MobyGames contradict this, so I assume Wikipedia is just wrong.
