Now as a remake, and not knowing their resources, I can empahtize with the difficult process. I am minor team member working in a subcontracted company for a certain AAA title with 3 letters, and grind can be bad. Its very easy to see why this game has so many remakes. Its a solid story with a good core concept
Now, if I were to buy this title and society wasn't so shitty to adult content games, I would make several changes. First up I would remove Eric. He never jived with the story, and you know a character is shit when you can't wait to be rid of them for the real story to start. All of the female characters, even the minor ones really add depth to the story and are not just part of the fuck list. Conflict is sweetest when the story itself serves as the antagonist.
Freeloading family had a very strong start and middle, but cracks started to show halfway near the end, and the bottom fell out.
