Rastaman please don't mini-mod per our forum rules.
Considering we've got some Trinity (AKA "MV Ace") functions, Trinity having feudal Japan tiles, DS+ implementing modern and feudal Japan tiles...Yeah, the addition of Japanese tiles is basically inevitable as an addition to assets. In fact, I'd go so far as to assume that it contains the same range of content in DS+/Trinity. It'd be ridiculous to boast about how much content it has if they didn't.
Also, I was wondering about things like the green bridges in that dialogue sample, or the florescent green castle using parts that clearly don't go with it. My money's on the tileset editor having a flexible hue shifting option.
