My take on H-games is that I wish gallery scenes are fully unlocked at the very start. Yes, I would spend many hours playing games like Slay the Spire to complete percentages and unlockables, but I would rather not spend more than two hours of blueballing myself on an H-game story mode.
Yep, most H-game RPGs are just mind numbing grind fests for scenes that are just two to five alt images. Some people get too caught up in the "game" part but they aren't even good at making it.
