"Gritty" does not equal mature. Obligatory:
Because that whole era of media is what happened when people started thinking that way. A better standard for maturity would be intellectual and emotional range. You need to have moments of levity to complement the grave ones, and you need to have whimsy to complement highmindedness. (Persona does well and FF13 does poorly on this front imo.)
I'd pick Dragon Age: Origins and FF6 as a WRPG and a JRPG that did this splendidly. Both feature an interesting, diverse cast of characters that all have their highs and lows and all have complex, multi-faceted personalities. Leliana's romanticism and apparent girlishness underscore her checkered past and make her reaction to the Sacred Urn thing far more compelling. Same with Oghren's boisterous oafishness and the meeting with Branka. Locke's whole roguish treasure hunter shtick does the same for his relationship with Rachel. Celes's personal growth and passion makes her suicide attempt far more tragic than if she'd been moping around the whole game.
Compare to Deus Ex: HR or the Witcher, where everyone's varying shades of "smug asshole," or FF13, where everyone's whiny and miserable all the time.
I've never read/seen Game of Thrones, so I can't really comment on whether it fits your criteria for "maturity" or mine. But yeah. A mature work is deep and complex, and works that just go for "gritty" tend to be shallow and immature. (Unless your definition of maturity is the same as the ESRB's...) Gear of War is gritty as hell, but it's one of the most immature games of this console gen.
