Yeah, no I agree, A is a good stopping point. (And likely the stopping point.) I guess I just worded my last post wrong. I'm just saying, theoretically, and with proper writing, there's still a lot they could with the series if they decided to keep going. When I mentioned S, I meant more the S format of a quasi-sequel as opposed to the A format of having 3 routes/title in more of a fan-disc fashion.
But yeah, I'd much rather they end it here than revert back to S.
