In my idle poking around things CoC-ish, I find that Chaosium has updated the massive "Masks of Nyarlathotep" campaign to a shiny three-volume full colour hardback edition for 7th edition.

That's all very nice, but the down-side is that it costs a bit over $NZ200, plus whatever they'll add for P&P.
Fortunately, CoC being as it is, the old version is easily playable with the latest edition of the rules if I ever feel the urge to commit to literally years of game play.

(I would like the new and shiny version, but maybe not $200-300 worth.)
