I don’t know if it’s pure nostalgia talking here, but games sites back then were made to look fun like they were part of the game. Verses now when they’re a dull and corporate.
The manuals as well. Loved the WarCraft III and Diablo II ones. They were legitimately part of the game experiences as lore was told there. Now the publishers don’t even bother to include a single sheet.
So many websites look like someone spent 10 minutes in Squarespace
And these days it's worlds easier than it was back then to make sites with complex designs and game-like effects and animations.
When I first started learning about web design, I came across this popular book: https://en.wikipedia.org/wiki/Don%27t_Make_Me_Think
And essentially you are taught to go against a lot of things you see in these examples and design things in the way modern websites are designed e.g. big call to action button, search bar on top and center, little clutter. Modern websites are meant to be more "simple" and "easy" as the web is now meant to be "accessible" to everyone rather than just for nerds.
