I finally picked up the new Kingdom's 7946 King's Castle and thought it would be fun to post some side-by-side pictures of it compared to the original 6080 King's Castle and a brief comparison/commentary of their similarity and differences. Link to Flickr
Number of Pieces:
6080 King's Castle: 618 parts
7946 King's Castle: 933 parts
Number of minifigs:
6080 King's Castle: 12 minifigs - (4 archers, 4 soldiers, 4 knights)
7946 King's Castle: 8 minifigs - (1 king, 2 archers, 2 soldiers, 1 green dragon knight, 2 green dragon soldiers)
Number of horses:
6080 King's Castle: 4 horses
7946 King's Castle: 1 horse + barding
Number of instruction manuals:
6080 King's Castle: 1 book
7946 King's Castle: 3 books
Both sets look very similar and have some very similar features. Both sets include a drawbridge and a gatehouse. Some of the differences are the 1-piece portcullis on 7946, whereas the portcullis was brick build for 6080. 6080 also had 4 more minifigs, all from the same faction, but 7946 had an actual king with a very nice horse barding. Both sets have a dungeon, with 7946 having a "break-away" rear wall so the prisoners can escape.
Overall, I really enjoy the new castle. My only real gripe was the over-juniorized instructions and for many of the steps, you put 3 or less parts on. They could have easily condensed it into 2 books. I love the modular setup for the new castle, you can take the sections apart and rearrange things. I hope Lego expands on this and gives us more modular sets to build into our castle similar to the blacksmith shop and armory that went with the Lion Knights line. The castle is also very stable, they added 2 connector pins at the top and bottom of each wall, which makes it much more rigid than the King's Castle Siege from the crownies. The color scheme is nice too, I like the red highlights.
Anyway, hope that helps, please feel free to leave your own comments.
