Mainly new cover art with the 2nd editions.
“In HQ2, the results table has the low roller get a Marginal in a tie. In HQG, the high roller gets the Marginal. These seem the same to me – what is the thinking behind the change?”
They do not have the same effect.
Consider a character at 4W against a very high difficulty of 12W. With low roll wins, if the character succeeds, they will almost always win. With high roll wins, if the character succeeds, they will only win if the difficulty roll fails or is below their roll. Much more likely the resistance will win, which is what you’d expect between the two levels.
