Does MP4 have a base unit for a commerce system.

[kato13]

I am trying to come up with some type of generic pricing for equipment and I was wondering if Morrow Project version 4 had any base unit of cost.

Currently I am thinking of using the "gold grams" system that was in Twilight 2013, but if Morrow uses something else I might use that.

Any thoughts or comments on base commerce units in other systems would also be welcome.
