I understand your concern. I agree with the need for one handed optimization for porn games. It sounds like nearly all the porn games you've tried weren't programmed with one handed optimization; allowing one to play the entire game with the left or right hand.
The good news is that there are game with one hand optimization.
- NLT Media; has about 15,000 patreons; they boast 1-hand optimization right on their website.
- Wild Life Single Player - AdeptusSteve considered it, but it wasn't promised. He saw how it can be convenient, and he pulls in around $100,000.00 a month in revenue.
As of 2022-2023, big game devs are starting to see the importance of 1-hand optimization. NLT Media was ahead of the curve.
By 2030, every porn game should have one handed optimization built into it. That's the future.
RPG Maker games can be played left or right handed, making them optimized for one handed game play mostly already.
Ren'py games do not have one handed optimization built in already. I talked to the creator of Ren'py a few years back, and he scoffed at the idea, but he has no clue how big the porn game industry is now compared to years ago. Whether he wants to or not, one hand gameplay optimization is coming to Ren'py.
(Anyone who reads this, don't respond to me looking to "be right", respond to me with the mentality of genuinely want to find what's right. I don't give a fuck if I'm right, or you're right, I only give a fuck about finding what's right, to make a better product, to make the end user happy, that's all I give a shit about. So if you make a good point, I'll agree with it, because it will help me. )
