SaGa Scarlet Grace is lowkey an amazing JRPG. Not "for what it is" or "for a SaGa game" or with some other kind of qualifier: it's legitimately great with one of the best turn-based battle systems I've experienced. Think there's a very good chance you'll enjoy it, Guillaume. I also don't remember a single playthrough being all that long by modern JRPG standards either, which is also nice.
If I didn't play Scarlet Grace, I probably wouldn't be that excited for Emerald Beyond based on what was shown on the Direct either, but my experience with the former has me all in when it comes out next year.
