It's crazy to think, but most people who work in the games industry now don't even like videogames, and I can guarantee most UI designers don't even bother to playtest the very game they made the UI for. Older games were designed by nerds, people who grew up reading comic books and watching classic action and sci-fi/fantasy films, full of passion and an appreciation for artistic vision and design. Modern games are designed by a committee of diversity hires and poorly-trained casuals, people who grew up watching sitcoms and browsing social media, absent of the curiosity and creativity older media breeds, and who ironically derided videogames as only for nerds.

I think it's definitely that but also importantly it's the result of technical advances allowing for people to simply not optimize things anymore, i.e. people are lazy. NES games and early PC games needed to design UI systems that both looked nice and conveyed necessary information, "cutting the fat" so to speak because there simply wasn't room to include all possible information like modern games have. Earlier games also required people to know what they were doing since most of them were designed in-house, so someone working on Fallout for example needed to design a specific UI that fit the aesthetic and provided information that they knew would be useful to someone playing the game. Modern games are all built by massive teams off of pre-existing technology. The UI designers just use presets and plugins, providing any and all information they think a player might need.

<Older UI
>Non-intrusive
>Mostly diagetic
>Only provide necessary information to the player (health, items, spells, armor, stats)
>Easy to digest (character equipment and skills are clearly equipped, items and text are clear and easily identified)
<Newer UI
>Very intrusive ((every single one takes place on its own screen)
>Non-diagetic (menus are all just floating icons or featureless boxes)
>Most provide a glut of useless information (online info, menu tabs, game settings, skin settings...)
>Visually cluttered and hard to digest (little/no organization to items and equipped gear, small text, homogenized design)

More women and casuals play videogames now compared to the past. Women and casuals enjoy playing dress-up and seeing how cool their character looks (especially in multiplayer games) so that feature has slowly grown more and more important in the eyes of game designers (and execs who force top-down changes based on market trends).
