It's complete? I do have a question.
As someone who played the OG game, what benefit is there in playing this remake? If the only difference is just gameplay-focused due to being an RPGM game, then I'd rather not deal with it.
Like... does this introduce new characters? new art? new good stuff?
If you played the OG that game is perfect because he takes the central element of the main game to make it the reason this game exists.
There is more than 700 monsters. While most have 1 or 2 scenes you can recruit them in your castle and interact with them to gain affection and unlock a lot of new scene (not only a loose scene like in the OG). They are not all of the top quality, but there is a lot of choice.
The story follow the same "route" at the beginning but the twist of the story make strange thing happen.
And after 60-70h of gameplay then you enter part 3 and then the game starts to go in 2 different directions where you can help the angel side or the monster side and after that there is a chaos route but that spoiler territory.
The feeling of the game is pretty good and the rpg element can be limiting but some people love the optimisation of it.
In my opinion, it's a great game for people who loved the OG and an ok rpg for people who didn't. The real blocking point is the protag and the femdom theme, but if you liked the first series then this game is pretty good.
I need to add that part 3 just got out at the beginning of the month so in order to play this part of the game you need a translating tool like mtool or over tool. But with the advancement of the machine learning, the tool are pretty good so most player are ok with this. If you only want human translation then part 3 is probably going to take 2-3 years to be fully translated in perfect english.
But you can at least try the beginning of the game in english and see if you like it.
