If you'd told me you had a library of 3d action-adventure games and fighting games and hated shooters because they were plotless, mindless gorefests, I would recommend Portal, Half-Life 2, and Halo. They are dissimilar enough from genre's stereotypical dreck that I'd recommend them even assuming your statement was completely accurate, and good enough in absolute terms that I think you'd be likely to enjoy them. I agree that there are a ton of awful VNs out there, just like there are a ton of awful shooters, but I hate seeing people throwing the baby out with the bathwater based on sweeping generalizations that simply aren't correct.

If you want more specifics: You complained about VNs as being "anime" and then said that all anime was about high schoolers. I provided recommendations for high-quality VNs that were neither anime nor about high school.
