A modern save file system wouldn’t change anything. Hell, I could actually event a really simple retry system for boss fights in RPG maker right now. It’s not hard. But it also doesn’t fix anything. Refer to my previous posts for why. The save file aspect just really isn’t that relevant. However, I do agree that typical JRPG systems aren’t well suited for fetish games. But you also don’t need to make a typical JRPG in RPGmaker.
If every bad end in an rpgmaker style game was the result of a dialog prompt choice and every dialog prompt choice autosaved? And you had infinitely many save slots? Problem instantly goes away and is solved. The fact that rpgmaker doesn’t offer this is just a flaw in the engine.
As for this, RPGmaker does let you do this. I can boot up RPG maker right now and make a simple story where you just make choices and those choices let you see different fetish scenes in the story as it goes along. RPG maker does offer this, and there are actually a fair amount of famous RPG maker games that do exactly this.
And honestly, yes, this doesn’t have the same problem. At that point the game just becomes a visual novel made in RPG maker that’s about exploring different endings for one story, and that’s totally, 100% fine. You can even mess around with it and make a really interesting game. However, it’s worth noting that you don’t have to do this. You can make an interesting fetish game in RPG maker while still keeping the JRPG aspects. It’s difficult, but definitely possible.
