The same way everyone in any industry takes credit for work done by other people.

And it's just product marketing. Most of the world aren't engineers. Boring them with technologies and specifics isn't how you sell products.

It isn't 'just product marketing' Their videos are ridiculous and prey upon people not being able to identify what they aren't seeing.

They made grandiose claims and diverted attention to things that didn't matter. How many games are using what they've done?

It seemed pretty clear that they were more interested in geospatial, real estate etc industries. Gaming is not even a sensible industry to break into given how fundamentally different the workflow would be to use this technology.

And sure it was a little over the top but then again so is most marketing.

That is 100% not true, their videos were of them running around in video game engines and pointing at low poly trees!

> Gaming is not even

They claimed themselves that two games are being made with their engine.
