It's hard to compare the two.I think what people trying to say is that both game debut in 2017 and GGGB managed to conclude with a huge amount of content.
It's clear why that is. GGGB has static characters with no initial customization telling a well made proper but limited choose your own adventure story. The bigger GGGB got the bloat slowed development down. At the end people were starting to get annoyed with the pace of her game because she would only have time to do one small branches story.
This is the Skyrim vs Witcher preference. Witcher 3 has no customization, but a rich story that is engaging. Skyrim story is SUPER generic, but it allows for customization which people, including I love. Thing is you can't do both unless you dump a shit ton of time and development into it, which porn devs cant afford to do.
Female Agent has customization which means it is much harder to write a story for and code. It's a mix of a sandbox that leads into a narrative story. I love the immersion this story has in the beginning but once the story gets going it gets disappointing. Specifically the sex scene descriptions given out generically, and are not unique for each sexual encounter. The problem is that it's hard to write a good sex scene when my character can be a skinny petite with a B cup and someone else has a 7 foot tall with a G cup. Sadly the differences make sex different and to deal with that you need skill and more time devoted to the sex scenes.
So I agree with you that this complexity is slowing down development and making a worse product. Don't get me wrong I like this game but each sex scene needs to feel different, and erotic. Sounds like the developer is now trying to redesign the game to have better sex scenes (whatever that means.) Sadly we don't know what that means. Is each sex scene going to be unique or continue with a modular system following a TITS style sytem? This has to be solved before the game can really continue, which means we are in for a long wait.
For me, the best case scenario is rewriting ALL the sex scenes to be unique. Note, you have to re-code the game to get rid of the old school modular system which people seem to be think makes boring erotica. That is a HUGE undertaking, going to take months. From then on writing new sex scenes that account for different sizes and such which is a slow process. I think it's going to take a long time to get there.
I hope this game makes it but it's in a bad place, and this stems from complex customization.
