I like the idea of dark nights (even though I'd probably poop myself in fear if anything jumped out at me). However, if we're riding around in hi-tech Omniframes with holographic AR displays, wouldn't night vision just be built in and projected in front of us? It feels like that would be a standard feature, especially if the frames were built with a mind towards mining. In the pure dark of a mine tunnel, I get it why flashlights and flares would be necessary. On the surface, though, I would think there is enough starlight/moonlight that a night vision system would give decent visibility without added light sources.
Hmm... Does EM-8ER have a moon or moons?
