It didn't start out that way and talked about in this interview
Transcription:
"The game has gone through stylistic changes too, evolutions, which I talk about a little bit.
I've talked about it on social media a little bit, but at the time when we started we were going for just, like, high fidelity realism, that was sort of Plan A, [it was] literally like in the classic video game 'better graphics' sense, you know, Marathon was gonna have better graphics then Destiny because it was the next game, and so that was a very natural thing and we were going to lean into material definition and fidelity and detail and all that stuff.
So the pivot from that kind of realism ambition, to a more stylized graphic simplified approach, that was the biggest most important change from an art directional art point of view probably in my career, and also for the project itself, and even when that announce trailer was made, we were still actively evolving the style, and so there was a very deliberate choice to not try to reflect the exact art style in that announce trailer too, so you know the game won't look exactly like that trailer, but it will have the same sort of inherit qualities, and I'm still very happy with how that trailer came out."
