On the question of scale
It's something that we can almost take for granted, but scale is somewhat key to miniature based hobbies, and is something that, as a designer making terrain, is a major headache at work. Conventional model design has a fairly straightforward approach to scale. If you buy a kit that's 1:72, you can be fairly sure that the model will be 1/72 the size of the original. If you tried fitting a 1:35 rifle to a figure therein, however, it looks ridiculously oversized, since it's nearly twice the size it should be. Scale gets a little more complicated when we get into railway modelling. At the core of model railways is the track. Of all elements in such a set-up, the track is the most mass-produced component. Tracks, in real life, however are far from universal in dimensions, with different gauges in Britain, Ireland, mainland Europe and the Nordic nations, to give a small selection.
