Glad to see they're still working on this project.
Admittedly I'm a bit disappointed to hear how difficult the modding process is, but I can't really say I'm that surprised. Wife Trainer has always been a very complex game, even back when it was still on the RAGS engine. Moving to Ren'py (or any other game engine for that matter) isn't going to change that amount of complexity.
The game being complex with a ton of moving parts isn't inherently a bad thing, but as others pointed out it's going to be a much harder sell to get any casual modders interested.
If I had to guess, the devs' decision not to take money for this project is also likely for legal reasons. I've always wondered how "Real Porn" developers are able to legally accept money for these types of games when they're using the images of real adult film stars. You see it on a lot of HTML games posted on this site, they'll have a SubscribeStar, Patreon, Kofi account meanwhile they're using someone else's work in their game without authorization. I'm no lawyer but that feels like trying to navigate a minefield to me...
Anyways, good luck to the devs and modders. I'm looking forward to revisiting this game since it's been a few updates since I've played. I'll probably add the Kagney mod too, thanks for putting that together Haseo!
