sideranautae said:I'm only commenting on MGT. In MGT Trav the Jump fuel is used exclusively for creating a hydrogen bubble. PP fuel usage is calculated 100% without reference or in conjunction with JD or JD fuel usage. In other words, the rate of PP fuel usage doesn't vary with JD use.
This is one part of the description of jump drives from MGT I don't like. I like to imagine esoteric fields and folded space, not hissing hydrogen gas. Your comment on PP fuel usage is correct. I like to imagine it is because the PP now powers the JD as it produces the Jump Field.
