Don't know if anyone's mentioned it yet, but Isolated With mom is a really good one. The problem is that it's abandoned. Still a good bit of content though. It always sucks to see when such great games are abandoned. Most of my favourite games never get finished.
I'd give it a 3 for story, 10 for renders so an average of 6.5. It's not the best AVN i've seen. But you might like it if you're into multiple LIs locked behind an artificial gate made by an idiot dev who thinks polyamory is unrealistic like all these slop games with the exact same plot and an MC who behaves the same as 10,000,000 others
