Also note that the gradient sky you see in the N64 version is also an image (tile #3979 in the Rom). So I am very sure they could have used a paralaxed sky if they wanted.
Ahh, I didn't know that. I think I've read in some FAQ (possibly at GameFAQs) that the lack of parallaxed skies in the N64 version was due to a technological limitation of the port's engine. Since it seemed a sound explanation to me, I never questioned it.
Today I've been looking through the pre-release shots from the official 3D Realms' preview packages for Duke3D, and what caught my attention is that even though in most of the old shots where the HUD has red lights/buttons on the sides those lights are "on", there's one shot where they're both "off", and another one where only one light is "on". Is there any reliable information as of what purpose did they actually serve? I almost thought that it could be some kind of damage direction indicator, or enemy indicator, but those are just wild (and probably incorrect) guesses.
