Silverlock review in Emerald City

Emerald City, a charming SF webzine, has a review of Silverlock in the current issue which helps explain just what fans of it see in it.
And I do still want the new hardcover edition.
I’d do an Amber game set in the Commonwealth, but I am not certain that the material hasn’t been covered by the Tuesday Next novels (The Eyre Affair, etal), which has, afaik, already been done in a game at least once.
