Yeah, I don’t feel foolish at all. I’ve explained this in other comments.
In summary:
I’m not claiming literally every instance is exactly what I’m describing, but it is a very common pattern.
Many of these ads are slight variations to test which performs better.
Many of the “which performs better” are run against long standing ads they’ve had to learn about how to advertise. They may never intend to release the games being advertised. They may know the ad does well, but they built a prototype game and it didn’t monetize, so they’ll never finish it or already killed it. But that doesn’t stop them from running the same ad but with a different visual theme to see which visual theme is more popular right now.
Some of these ads are not run by dev studios but by advertisers or publishers.
Markets are not static - interest in themes, visual styles, and game genres are all extremely “seasonal” and keep changing. They do not “know their market extremely well” because interest keeps shifting. Companies will constantly run ads just to gauge what genres they should be thinking about and to track trends over time. IE, they may run the same exact strategy game ad for many years straight to determine the long term stability of strategy games. Without caring about the specific game idea in the ad itself.
I don’t feel foolish, nor do I think it’s “clever”. I just know from first hand experience that this is how the market works.
