Maybe Quint meant the lighting, ground textures/look etc. |
But yeah, Bungie did some amazing work when it comes to art and backdrops. Halo 2 SP had some of the best Skyboxes/artwork in the series/videogames in general, esp the flood levels on Delhi Halo. Halo 3 was pretty great at times too.
Reach was when Bungie dropped the ball IMO.
