Do think that in a planetary colony every one would be in mechs. when there not in side the base or do you think that they just be in suits to protect them from the atmosphere.
It really depends on the environment, and resources of the colonies. Do they need mecs to survive outside, or will simple space suit be enough? For example, the if your colonizing mars you probably only need a suit. But you need a high science fiction level mec if you ever wanted to walk on the surface of Venus. If they do need mec to living on the surface, do they have the resources to give everyone mecs or can only a handful of people afford one?
