It's interesting, that we have sort of a weird dichotomy on this side. What I mean is, we have many games that are objectively not good if you factor everything in, but still get very high ratings, and then we have games that have a certain quality and yet often struggle with ratings.
There are games with really abysmal writing and a barely existing story, with the same few models used for every one of them, with the consensus being that the larger tits and arses are the hotter the women (and don't get me wrong, I love me some voluptuous babes, but there is a point where a breast becomes a gym ball), the sex scenes consist of one or two short loops, without any additional dialogue or exposition, and those games get dozens of 5-star ratings, and I guess it is fine, if you just want porn images in a game and don't mind the ridiculous proportions, that's up to you.
On the other hand, though, we have some really well-written, well-made games with a great story and good characters and yet while most of them rate pretty high, they seem to be rated with a different measure.
Some reviewers set very high standards and find perceived shortcomings enough to detract one or two stars.
And yes, it is fine if you rate a game like this with 3 or 4 stars, and maybe it does deserve it, and you certainly have the right to do it, but I also think one should maybe consider the way a lot of the games here are rated, the effort a lot of people put into their reviews.
"There is no content and this and that and this isn't that great, but I think the game has lots of potential 5 stars" or
"the mother of the MC who might become at some point a possible LI has dared to kiss her husband, that slut! I'd give zero stars if possible!!!" or
"no animations 2 stars" or
"no sound 3 stars" or
"the game contains this or that content that doesn't adhere to my personal tastes, so it's a horrible game, 1 star." or
"the game has a harem, and so it gets my five stars."
We've all seen these, I think, and maybe, just maybe, consider the average quality of the games we encounter here and then factor that into your review as well, and sometimes it might make sense to give a game one star more, just to make clear, it actually IS a good game, not just a game you enjoy for whatever reason.
This isn't directed at a particular review or reviewer, just something that I've noticed while reading through the reviews for some of the better games on the site.
