There's this thing that devs do where they think that sci-fi environment needs to be as visually complex as they can make it.
There is a lot of grime, rust and overlapping maintenance on a ship or oil rig but it isn't universal. The mess or sick bay are usually nice and clean and open, sure you're never far away from pipes, wires or machinery but you're hardly in the bowls of thing at all times. Another problem with the "lived in" look is that it never looks like it was never new and clean.
Then there is the over designing of everything in sci-fi games. The 343 Halo games are a prefect example of this, and it makes everything look too complex and bulky. Sometimes less is more and for certain items like say a fire extinguisher, more lights and polygons just make them look needlessly over designed.
I don't want the devs to change the very dark and industrial look for the Ishimura but I can already see hallways that are fairly simple in the original being filled with stuff to the point where a simple lighting fixture or wall panel is made of 1 million polygons and has 8K textures for no real reason.
I feel like so many designers took the wrong lessons from Alien. The Nostromo has a very 70's NASA look to it and while it's cramped and full of lights and buttons, it's still well lit, has clear hallways and looks somewhat comfortable. The Ishimura on the other hand looks like the refinery that the Nostromo was pulling at all times.
