try to create a complex mod = Factories/modules in one station/grid

...or S(mall) and M(edium) for that matter. I haven't used either, but every time I browse your collection, I have to stop and figure out anew what the S and M stood for :)

M(ine) and S(tation) are only different in the Diamond process chain. It has nothing to do with Single- or Multiplayer

If someone is only hosting a game for a friend or two, rather than having a dedicated server, should they use "M" instead, or is that only used with dedicated servers?
