Because that's what they did, or how it was done... doesn't make it right.RPGs outside Jrpgs have a much higher average sale through rate.
There's nothing flawed about either, they came from different styles and game design approaches historically when both were mostly found on separate platforms, and formed when that ended.
It has nothing to do with being turn-based that nonsense came later. Plenty of turn-based Wrpgs were contrasted to turn-based Jrpgs. When a Wrpg in the mast used the Jrpg formula it was obvious and noted in reviews or preview coverage.
All I am saying is that turn-based RPGs, make up a majority of the kinda RPGs the Japanese make. And the market for that type of RPG has been shrinking. Its just like that phrase rouge like... this is something that's done a lot in this industry. Whereas, what we are calling rouge like today, is basically what an arcade or even a simple scrolling shooter was 20 years ago with some procedural elements sprinkled in.
