That's the 21st century, and 'No Child Left behind' talking. The truth is the truth regardless. Personal experiences aren't "truth," that's just a pathetic copout. It's what enables scared and weak children to play make-believe for their entire lives. To never move out of their mommy's basements. And to keep Twitch THOTs and Patreon scams going indefinitely.
Unfortunately for you, life ain't T-ball, you won't get a trophy just for showing up, and being obstinate for the sake of it won't help you create a must-own game in a genre packed full of mediocre bullshit.
Every single one of the must own porn games are made with the convenience of Ren'Py, which means that NONE of the must own porn games are made using Unity. And that is the UNDENIABLE TRUTH!!!
What are the odds that you will be the first? Time will tell, but my guess is that they're pretty low.
