In no particular order, it is Microsoft, EA and Activision. I know I am going to get a lot of hate, but I love multiplayer games and these three publishers are the best regarding it imo.

Atlus (technically a part of Sega, but yeah...), From Software Namco Bandai, Sony.

Devolver Digital
Nintendo

Nintendo, Atlus, Namco Bandai

Atlus, Nintendo, and I don't know.

Aren't publishers the ones that make every game objectively worse by demanding focus testing and additional monetization?
The only thing publishers have going for them is buying developers, which doesn't really take that much skill. I'd rather not judge people by the things they bought and rather by what they do and what publishers do is usually terrible. It's not like games become great because of publishers, it's rather the opposite.

One big exception are probably some of the indie publishers like Adult Swim and Devolver who help awesome games without sticking their dirty paws in them.

Nintendo.

atlus,nintendo and rockstar.

Sony, Namco Bandai, Take 2

Nintendo, because Nintendo.

Namco Bandai, mostly for the Tales of series, but I do enjoy a lot of their other series.

Koei Tecmo, because Atelier series.
