Hello there, i never said unreasonable, i said is a huge ask, which it is because it would need to change all the cgs of the characters involved and their way of acting. The people that want to play without interacting with them can, as no futa character is obligatory for anything. There's no cuckoldry on the mc, there's shares, which is not the same, and the player can decide not to do it.
Futanari enjoyers get their content and the ones that dont like it have plenty as well, theres 4 futas in a game with over 40 characters.
In regards to the game using AI, is not a simple "touch up" it takes time, the assets are not simply generated and given a small touch up, there's a lot of after gen work.
