Im a big proponent of this game, but I would have to say that I agree with the guys saying the grind sucks. Even while using cheats I found myself with large chunks of time between actual scenes (About 45 minutes). Of course a lot of this had to do with having to follow a guide, but I didn't do any side objectives ever unless it was tied to a scene. I could only imagine how long the downtime is between scenes is when your playing a non-cheated run and you don't have a guide. I personally think the game would be unplayable. I don't mind having to work for my lewds, and I understand that it takes time to build story in RPGM because of how its designed, but god damn its poorly managed in this game. Also the fact there's no text skip makes all this just even more frustrating. I have talked to the Dev and they did confirm that after they finish the story they would add more buffer events to the story, so I guess that's the silver lining.
