Yes. I play these games because porn is better with immersion, and games (or even KNs) are more immersive just watching short videos, or full porn films with actresses who can't act.
However, many game devs add branching ("YOUR CHOICES MATTER! ZOMG!") without realize how much harder that makes game development, or they are attemping to recreate a AAA game experience that they themselves enjoyed. But let's face it, a single guy in his basement googling up python snippets from stackoverflow is not going to create Dark Souls here. The gameplay is usually not fun and it just gets in the way of the content.
Add that to the fact that even a $5/month patreon usually ends up being hundreds of dollars over the life of the game, and I'll be damned if I'm going to spend hours fucking around in a terrible UI trying to uncover the last bit of content that I paid for. Much easier to grab a plugin and just follow the prompts. It's not like deciding "Hug Her/Do Not Hug Her" is a great moment in game play that I feel bad for missing out on.
