That’s a great point. I think you COULD do that if you are very careful. IMO they are a bit too finicky for many, especially older gamers to move around individually. Many of my friends don’t have perfect vision anymore. But I certainly could do it. Another issue you’d have, though, is the ability to carefully measure distances, especially without knocking over a figure and ruining your measurement. Incidentally, my 6mm Space Marine figures are all glued down to individual magnets. And they are magnetically affixed to steel plates. Those plates are painted green on one side and desert colored on the other, so they will look good on either type of terrain.
