Think the problem here is that they are showing unreal 5 capabilities. You can check the rest, and meta human.
It’s 2023, when was the matrix demo? That was also very impressive but it’s about time we see the tech in game.
They showed that EV jeep driving and that was gameplay.
This was an Unreal Engine show, for Epic, by Epic. They've brought in partners to show off engine features, in this case Ninja Theory to show off the Metahumans tech and facial animation of Metahumans.
This is not the context for revealing free flowing gameplay for a first party title, itself a marketing tool.
Look at the post above me. This shit is false advertising and we already have idiots thinking hellblade will look like this (despite having an actual gameplay demo that looks far far worse). This kind of tech demos aren't revolutionary. There is nothing new on display.
Facial animation isn't new. It's been in games for decades.
Unreal Engine Metahumans is relatively new, and animating MetaHumans with high resolution camera rigs is new tech for MetaHumans that's showing up in a few months. That is what Epic sought to demo.
The real issue is that some folks stubbornly refuse to understand the context. This is GDC - Game Developers Conference, and it's all about sharing tech with developers to go out there and make games with those tech.
