There is a parallel between High Steel and SimCity: both made a game out of a level editor. In High Steel, it is not a city that you build, but a single skyscraper. Unfortunately, there are lots of strange monsters (where do they come from?) that are adamant to thwart your plans, and objects are constantly falling from the sky.
High Steel is remembered better on the 8-bit platforms, but it was the Amiga version that caught my attention: its graphics were created by Mark Jones, of Darkmere and Daggerfall fame. It was not his first work, but the first where he alone was credited for the graphics.
Frustrating it can be, take one step too close to a banana skin and you can go slipping off your construction and you can guess what happens then, also the occasional thing falling out the sky may hit your nice shiny helmet but it'll still leave you stunned for a moment, and vunerable to any other nasties that might pop up to kill you, but it all adds to the game, and strategy required to get anywhere, if there wasn't anything trying to stop you this would be one very boring task.
