When fans saw the first trailer for Cyberpunk 2077 at this year’s E3, a vocal minority was upset that it looked too bright. Even author William Gibson thought it was missing a certain something. As it turns out, that something was a complete day and night lighting cycle.

Today’s world premiere gameplay trailer, which came in around 48 minutes long, was narratively the same as what the press was shown at this year’s E3. The only difference was the lighting, which included deeper shadows and more substantive high dynamic range lighting than was shown in Los Angeles.
