I think Concrete Genie, and Days Gone are pretty decent tbh.
Like, I dont think Nintendo can make games like those, even if they tried.
(granted Nintendo does things, Sony studios cant do either)

Still, think Bend Studios (days gone+syphon filter) and Pixelopus (first big game, Concrete genie), are A ranked atleast.
Both of them have potential to grow too, esp Pixelopus.

Tbf going from their recent game/s Days Gone didn't review all that well (in comparison to their top studio's) and commercially didn't sell as well as expected for them as a AAA game. I'm going to guess that's one of the reasons why the sequel wasn't green lit. And UC Golden Abyss, which suffered the same fate; though that was a more budget orientated game on Vita so take that as you will.

Your confusing review scores with quality of production.
Bends of more than capable of makeing big AAA games.

Days Gone was basically branded sexist by reviewers in a cirkle jerk, and alot of them then went onto give it less scores, not because of its quality, but because of political correctness or their own personal political views and such. 

Yeah they are capable of making a AAA game but how well they are received is a bit part of big part of how good a studio is, no? I'm just going from their recent games and output. The other stuff is fluff, its either the game does well and sells or not. There was a tonne of controversy towards TLOU 2 and a massive leak of the story but the game still sold several millions.

Like a publisher wouldn't put one of their top studio/s on (TLOU) remake instead of making a new game from the get go.

I`m plenty sure they are capable of doing AAA. I guess like Sucker Punch they still need some investment on increasing the team to iron out the details and deliver a very solid product (I liked Days Gone a lot, but there are plenty of faults and bugs or at least were on the original plus the BS fuel for the bike, and for me if SP had the budget Ghost could have been even better than TLOU2, love the concept, gameplay and ambience, all perfect and creative, but on the small details they missed, like you floating through steps and the like).
