External market at M-200%.

instead of a market, another useful object could have been generated, which could be used.
that is, part of the value that is spent on the market simply goes nowhere and does not bring any benefit to the player + it also takes up space.

it's like a cake for a diabetic, money (value) is spent, space in the refrigerator (takes up space on the map), but it cannot be eaten (used).
