I was all set to run Thousand Thrones from the last edition of Warhammer, but the new edition was just too shiny to resist, and I think the new rules are much more fun! However, that being said, I am pondering ideas on updating the old rules in the Thousand Thrones book to work with the new rules.
Has anyone come up with some decent coversion ideas? Even the value of money has changed, but that was the easy conversion... Old gold is a fifth the value of the new gold... it went from 1gc is 20 silver to 1gc is 100 silver.
For skill checks I have come up with:
Old -> New
Easy +30 -> Simple 0d
Routine +10 to +20 -> Easy 1d
Average +0 to -10 -> Average 2d
Hard -20 -> Hard 3d
Very Hard -30 -> Daunting 4d
Modifiers to any tasks don't need to be translated directly (a -10 mod from the old should be about 1 misfortune die added, but you could base it on the situation rather than the old modifier value to gague how many black dice to add).
Making up "new" monsters should be relatively easy butwhat about characteristics? An old edition characteristic divided by 10 and round down might work. (36 STR old = 3 STR new)
Wounds seem to translate directly.
What about diseases? There aren't any diseases in the new edition. I suppose it might be simple enough to mirror the disease effects from the old edition. Base resisting the disease's effect on resiliance, maybe.
