These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Machines Wired For War
Game Breaker: You could zoom in to control your Technicians to cram extra ones into your labs (which can normally only contain four), increasing the lab's research rate beyond normal levels.
Ugly Cute: All of the Machines have faces, as demonstrated by the Reaper page image. The more advanced a unit is, the more 'eyes' it has. A simple low-tech scout has only one eye, but the Knights (some of the heavier combat units) have three. Really advanced units have four. Combat units are permanently angry looking, as our Reaper friend up there again demonstrates. Technicians, on the other hand, are stuck with looking absolutely terrified. Resource haulers look about as smart as a stack of bricks.
