The first time I played I did it with full color and English dub, and it was good, but it kind of suffers from the “Pick the cat turds out of the sandbox” issue that almost every single one of these games do, where eventually you’re just going from POI to POI on the undiscovered portions of the map and everything gets kind of samey after a while.
I don’t know if playing in Kurosawa mode would be a fresh enough experience to hold me through a second playthrough.
