It all looks great. That’s kinda the expectation tbh. It does look good, but all games “look good” at this stage. This gives rise to the other question about can it look good and be stable, even on lower end hardware (ps4/x1 and mid/low pcs) for release.
But a video is a video. I realize it’s so early and am not knocking it for lacking gameplay footage, just that generating a video in-engine is not representative of gameplay, or gameplay elements.
