While the dev is a notorious perfectionist, and will overhaul until the cows come home for that reason. I definitely don't see him adding one scenario and calling it a day for that same reason. He's a perfectionist, and perfection takes a massive amount of time. He's basically the maximum level of "quality takes time." Like the extreme hypotheticals often used in philosophical discussions come to life. A would you rather that actually exists. Would you rather have a dev that will slap together 10 games in a year, or one that will meticulously design 1 game in 10 years? Me personally, I think he should just let some of his fans work with him to lighten the load. Either that, or sell the source code so this can become a modding community.
I'm getting contradictory vibes here. On one hand you ask if I'd rather have a quality game no matter how long it took, on the other hand you propose that he, a supposed perfectionist as you call him, outsource his work to imperfect strangers or even sell it to expedite development.
Honestly, I think he's just lazy or demotivated. Seems to be the type who cannot say no to something he's promised, so he just slowly chips away at it, a few hours per month, whenever he gets that speck of motivation. Cause frankly speaking, the majority of the assets are all already there. The early dev version featured Elulu's model and extensive repertoire of poses, expressions, blushes, sweatdrops, etc... It even had early sex scenes.
All he's gotta do is write the scenario, then translate it into conversations with sometimes adding a few dialogue choices and utilize the majority preexisting art assets and poses. In my opinion he's dong a great job leeching off his Ci-en supporters. Not that I care. I'm not invested. Just saying as I see it. Ultimately it's my opinion and I could be completely wrong. Who knows what goes on in his real life?
