I'm an obsessive VN player, and I doubt there are many here who could match my experience. However, there is one issue I've more or less deliberately closed my eyes to when it comes to VNs... and that is the sheer amount of anti-feminist propaganda inserted into untranslated Japanese VNs in general. There are a number of major, really obvious examples of this, and I'll go ahead and describe them for you.
1. The 'female teacher who never gets married because she acts too much like a guy' archetype. This isn't even a heroine archetype. It is just a side-character archetype... but literally the most common non-heroine, non-protagonist one in existence other than the 'idiot friend' one. How is this anti-feminist? First, it assumes women with certain qualities - hard-working, focused on their jobs - aren't attractive. Second - and more insidious - it assumes that all such women should want to get married, so it is something of a double-whammy.
2. The 'strong-willed heroine who becomes completely submissive the second she and the protagonist become lovers' archetype. This is perhaps the most insidious of the heroine archetypes when it comes to this issue. This is more or less a manifestation of the hidden widely-held Japanese male belief that even the strongest woman secretly wants to be dominated by a man. Yes, there are plenty of otherwise strong-willed women that use mild SM as stress relief, but the same can be said for men...
3. Otome games. Yes, I know some would protest this, but it is really obvious, when you play them. First, almost all otome game protagonists are easily-dominated wilting lilies or women who become so the second they meet a strong, handsome man. Second, even those that aren't spend a ridiculous amount of time being 'rescued' by men (Damsel-in-Distress Syndrome). Third... exactly how many otome games do you see that appeal to women who prefer to be dominant, in general?
There are any number of such themes, archetypes, and concepts that demonstrate this little reality, but it is something you should probably keep in mind when you think you are going a bit over the edge playing moege, thinking real women might be like those on the screen. Remember that while some women really do fill the archetypes, they are exceptions, not the rule. At the same time, assuming that they should fulfill those roles/archetypes is one habit we probably shouldn't import from Japanese otakus, despite our taste in games, lol.
