I played all the content of the original game at the time, and now I have tried this one, it has many good things and good potential, I also miss things from the previous one, many things, some may be fixed over time, others I don't think so.
Good things:
-Otsu
-More Oirans
-Combat support class
-A much more worked and careful story
-Animations
Things I miss:
-The big amount of content that was in the other game.
-Stance combat model.
-The blonde Fudeyo (new look is good, but isnt Fudeyo)
-The old Kisayo (she was always cold but the new Kisayo displeases me, the old one seemed like the only thing that mattered to her was the MC, The new one seems like she's more interested in being with the MC than the MC himself.)
-The dance job (I never whored **better not spoiler(the 4º Original Oiran)** in the original but she earned her salary dancing, now she can't, when she will become Orian it will either be an expense or she will have to take clients, in the previous game it was solved by having her dancing)
-In the previous game the feeling that the Oirans even if belonged to you, were at the same level of romantic interest as Kisayo and Nekomi regarding the MC. In this game it seems that we will have to choose between Kisayo/Nekomi/Otsu, and that Saka/Yura/Fudeyo/Oirans are just toys for the MC.
But overall I really like the game, as much as the original, and it has more potential.
PD: Truly, i dont want whoring **better not spoiler**, but, i dont want she cant gain money. :s
