IC: 7th Sea 2nd Edition
The second edition rules facilitate storytelling. They moved from old school situationist style to story/narrative focused style. It's no longer 'can I do XXX' when the dice are rolled, but it is now 'what happens when I do XXX'. Big shift and IMHO better for crafting stories.
Having said that, I loved the first edition lore. I loved the metaplot, loved the fact that different groups had different knowledge about the metaplot (not all of it accurate).
