True but the hype gets to large and the games end up getting spoiled to easily. In the olden days you got an announcement, previews, interviews, and it was released.To be honest, most of this is basically playtesters paying for the privilege.
For people who just want to play the final product, the only need is to wait.
I'm fond of how Bethesda announced games like Skyrim and Fallout 4. They used E3, showed a few videos, and it was released a few months later. Perfect combination.
Early Access works completely different.
