Honestly, sometime trying to mod stuff like can be harder than making it from scratch, with the possibility of messing up a dozen other stuff. Maybe not so hard if he already familiar with the game structure and whatnot.I'm just curious if it's possible for you to implement some variations in scenes during the combat sequence. I have absolutely no idea how hard it would be to repurpose a couple of existing scenes into the battle. Also if lust system can be nerfed a bit. That would definitely make the battles not feel like chore you have to grind through. It's just a suggestion - from a guy who has no knowledge of the work that needs to be put in to make it happen.
I for one, left the with a bad taste in my mouth wanting to make the for what it could, thinking of sketching up my game dev skills and making a brief demo using the images from the original. I'm not wanting to devote to make a full game either, so it could good if someone wants take it up after I make some base for that.
