But for modding purposes it's a pain.
My point is that the dev didn't really care about moddability (or the game codebase would have been structured very differently), so that entire discussion is pointless. But anyways...
Considering the way everything is implemented (I was a while ago trying to fix the naming of the variables from JP to EN but there are way too many instances of hardcoded strings to make this doable without spending ages, but I got a good idea of how stuff works) this thing was already barely running when it got released.
It looks like the dev started with a lot of temporary solutions which progressively became permanent the more he was working on them. Good luck trying to expand on this, everything in there is running on hopes and prayers tbh. Yes we got a monster generator but there is no proper system for retargeting animations which, for example, makes implementing new poses an extremely long process (to not talk about having to reposition the pieces in some ways, which could be done almost automatically, if such system was in place it would be just a bunch of vector math transformations).
There is no proper inherited behavior across pieces either, everything is hardcoded. Save for body parts which instead use reflection for addressing, (in the worst possible way aswell).
The codebase is so fucked up that my original idea of implementing a GPU driven renderer kinda fizzled out after a good look at the codebase. It would be possible (at the very least, something like ILGpu could be implemented to avoid having to deal with handling a new surface creation and the whole OpenGL/Vulkan/DX pipeline setup and management), but heck it's a giant mess.
the performance is not an issue for me
Err, dunno, if you play it windowed on a tiny window maybe. Unfortunately I've got a 4K screen and even keeping it at 1/4 of the screen size, this thing maxes out my CPU while barely hitting 15 fps. Performance is absolutely horrendous.
IKR... I love the concept and would love to explore it at some point, but aside from preparing a library to handle creature generation, I haven't started yet. And with recent Visa/MC endeavors, it's always less and less enticing to even think about it. Which sucks, the concept has so much potential... And I don't think I'm alone here, current market situation is very "meh" for anyone trying to come up with some niche game ideas, even if they could be potentially successful.
