Manji Maru was the second RPG for the PC Engine right? The guy with the multi colored hair. That one definitely had higher production value and better graphics (it was made in the 90s, Ziria 1989) . Either way Im having a great time playing Oriental Blue and getting 'eased in' to the whole asian style RPG.
After this game I may just beat Legend of Wukong to see how the Chineese play their RPGs.
