Second, Morrowind from 2002, which had basic information at the bottom of its first-person (or optionally behind-the-shoulder) view but where pressing the right mouse button would instantly pause the game and bring up four windowed menu screens, which could be resized and moved around as desired. The image below is from Mobygames, and the windows have been moved and resized from their defaults, but it demonstrates the separate menus for inventory, magic, the map, and character statistics.
Morrowind's resizeable and moveable interface windows were such a good interface, and the perfect example of why PC interfaces making full use of mouse and keyboard capabilities are infinitely superior to console interfaces designed around the limitations of a controller.
Morrowind's interface has all the information you need on the screen at the same time. If you want the map to be bigger, you increase its size (in this screenshot it's much larger than the default size, I never increased it beyond its default - but if you want to, you can!). If you want the stat sheet to be bigger, yep, you can resize it too!
It doesn't even need to fill the entire screen:
This flexibility was great in 2002, but it's even better in 2019 when widescreens are commonplace. With the additional screen real estate given by a widescreen running at 1920x1080, you have more space to rearrange the interface in whichever way you see fit.
And unlike modern RPGs with console interfaces, the amount of clicks you need to get to the thing you want is minimal. Wanna check how high a certain skill is? Wanna select a spell to use? Wanna change your equipment? Right click to open the inventory/stats/spells screen and do what you need to do. It's all on the same screen, not a dozen different menus you have to scroll through.
A PC keyboard has 101 keys. A mouse has 3 buttons, a scroll wheel, and the ability to point and click anywhere on the screen.
A controller has... what, like 4 buttons? 6? And some funny direction pad thing that works kinda like a 360° mouse wheel?
Good interfaces make use of the capabilities of mouse and keyboard. Console interfaces are bad by default.
