Stood the test of time: Nintendo's internal studios. Basically, all of them, or at least the main ones. Even Mario platformers in the last 15 or so years like New Super Mario Bros. 2 and New Super Mario Bros. U were still quality games despite playing it pretty safe and lesser Mario platformers. Mario and Zelda are strong, Mario Kart is strong, DK had a great 3D platformer, etc.
Fallen off: Naughty Dog. The Last of Us Part II had a poorly done story but great gameplay. And now, Naughty Dog games are taking forever and have less variety.
Those came to mind. If I have a few more worth saying I will make another post.
