I really enjoy this game. When a new update comes out, I will start playing it as soon as I can. Updates are regular, and reasonably meaty (I believe we are shown two new days every two weeks, with each day having multiple encounters if you choose.
People point out that there are too many women; this may be true, but it does seem like the dev is starting to better show us who are the main girls, and showing them to us regularly. While some plot points (the MC's super-potency, local drug stores running out of pregnancy tests, etc.) seem to be developing slowly, they are developing. My expectation that the MC will have at least 10 buns in the oven before Tanya delivers may not pan out; we'll see.
It's also true that if you're primarily here to see the MC and his titular grandma get it on, you have to be patient still. That said, one can't say that there's no progress there.
The MC, generally speaking, is a Nice Guy. In the real world, this isn't a magical pass to all the sex one can handle. To the best of my knowledge, this story isn't happening in the real world. Some women fall for the MC as a sequel partner immediately. Others (Amelia, Allison, Shizuka) love him dearly, without immediately falling into the sack with him. There is some balance.
