Nintendo seem to be the only company in gaming that seems completely solid at the moment. With their head count actually increasing by a few hundred.
I believe other platform holders still have a lot to learn from the OG.
First of all, they keep their costs in check. Take note PlayStation.
They do not allow their budgets to bloat, hire additional writers needlessly or pay narrative consultants. They don't feel the need to expand the maps of their games to absurd extremes and fill it all with busy work... Usually.
Exclusivity is a key pillar of Nintendo's game plan. It has been ever since the Nes, when Mario was the pack-in.
Exclusives are what define a platform and grow people's attachment to the company.... Without exclusives, you have no identity and the relationship to the customer is weak at best, usually nonexistent.
Creativity is the last part I will speak about here. With each IP, Nintendo has used their creative and loyal developers to reinvent the offering every time they release a new game. It is not simply "Mario has a grappling-hook this time"... No, there is usually some deeper gameplay changes that are constantly evolving through the play through.
Santa Monica Studio is the closest of Sony's studios to do his with GOW.
