Those days are gone forever, only a small number of games offer free demos, most of them are indie games.
Back then companies also tried to release games without any big bugs, nowadays they don´t care and even plan to fix their broken game in the first 6 months after it´s release.
Also back then, companies released content patches like new maps and stuff like this for free, that´s what we call DLC now. But to be fair, game prices are mostly the same as they were back then, but the developement of games costs much more today.
And then there is also the press...I mean a broken/buggy game like Cyberpunk 2077 got so many GOTY reviews 1-3 days after it was released, it was a broken mess, not only on the consoles. But who cares?
