Nintendo certainly isn't a specialized developer. They make action-adventure games, platformers, shooters, RPGs, brawlers, Racing games, etc...

I know you love them, and wish to include them because, you know, there's never enough praise for them since they created the universe. But they're still no specialists.

In any case, from that list, I'd say From Software.

I don't think you understand what I'm asking. Thanks for the passive aggressive comment though.

I don't think you understand the meaning of the word specialized. 

Nintendo is known for releasing quality titles ranging from multiple game styles. Not just platformers.  Hense, they're not specialized.
