Sorry, guess it was a bit of a vague question. Mostly referring to content; thoroughly enjoyed everything the original had to offer, so I guess a better question would be "is this version caught up with the original, and if so, have they removed any content from it?"
Each mafia's story isn't implemented yet. The club fights aren't implemented but I have a hunch they will. Other than that, I think the story has caught up, with some changes (like, I feel in the original your father was a good person deeeeep inside, in this he is a straight up asshole). The girls you could fuck in the original, you can already (exceptions are Laura, Sarah, and I don't know if the mafias gave you more girls since I stopped playing after choosing, but if they did, then they are not yet in the revamp), and more girls became available to fuck. There are also things to do that I don't remember seeing in the orihinal game, like working in the hospital, the mechanics or as babysitter (and, of course, fuck girls in the workplaces). The only content from the original that I missed was the possibility to put aphrodisiac in the food when you had to make the dishes at the old home (and I don't think this will ever be a possibility, since at this point of the story you are in a new home and basically Maria and Lucy do all the chores, cooking included). But everything else that I can remember is included, and more have been added.
EDIT: I don't know if in the original you could already fuck Tyna. If you could, then not yet implemented
