Nintendo has always primarily been known for its great games as well as its pioneering hardware and great business decisions that don't follow the crowd. There's a reason for that and it's unlike a company like Sony which primarily develops hardware and has little internal output in terms of software (in comparison at least). It's because Nintendo as a company has many creative minds and artists who are not only talented but work hard to ensure their games are as polished as possible (not that Sony doesn't but Nintendo has more internal teams and loyal second-party developers). The games that are produced have been consistently some of the most critically praised in whichever era they release (although publications that are owned or mainly about one of the major hardware developers are often biased in favor of that hardware).
