More than just that, you spend most of the game outside the castle.
Ultimately, i'm not saying that JUDGEMENT IS CANON, PERIOD. All i'm saying is that i interpret it as canon because at least imo, nothing there contradicts canon. It's just that for many old characters, that's the only source of "personality" they have. Judgement and GoS are all Simon has (maybe SMB idk if people talk there), Sypha didn't have anything else until the show and that's it's own universe (Well....outside the pachislot...erotic violence baby)
