IIRC the big problem with most 'old' games is the card printing, and this is likely why SH is a 'limited run', as they don't want to commit to keeping something with so many card sections in stock. Again IIRC card actually costs more to produce that figures, which might be one of the reasons why GW's latest terrain offerings have all been plastic, as in the long run they might actually be cheaper to produce than card buildings, etc...
