Pathfinder Map Pack: Starship Corridors [RPG]

I have to admit that there is truth in advertising when it comes to the Starship Corridors map pack.  All 18 tiles contain corridors (in a "dirty/old grey steel" aesthetic) with a variety of configurations--straight lines, four-way junctions, elbow bends, etc. A few of the tiles have something different: one is lined with (what I think are) spacesuits, another couple have computers or ladders going upwards, and one has an exterior door adjacent to a forest scene.  Although there's nothing wrong with the set per se (and it makes a good companion for the Starship Chambers pack), using this set isn't really going to be any better than just drawing some roughly parallel lines on a blank grid.  True, the tiles are more attractive, but setting them up in exactly the right configuration (and keeping them from sliding around) is probably more time-consuming than it's worth.  (at least, that's been my experience the couple of times I've used them.) I'd label them as "fine, but inessential."
