You know what I mean. It's E3, and a developer drops a huge bombshell announcement, but... it's just a name plate, maybe an animated teaser with the main character speaking.
After that, it's dead silence for 2-3 years, maybe even more, before we see even an inch of proper gameplay. Between the announcement and the gameplay we MAAAAAYBE get another animated teaser showing a bit of action, but no gameplay.
Why do they do this? Why don't they just wait to announce a game until they have actual gameplay to show off?
Some examples of my mind:
Metroid Prime 4 (This can be somewhat excused as they had restart development)
Elden Ring (Seriously, where is it?!? It's been years and all we have received are cryptic teasers, not even showing much of the actual world)
The new mainline Elder Scrolls game (Don't really care much for this as I never relaly enjoyed their games)
I guess it's to build up hype, but what hype can be built up with just a title and not much else?
