First off, I've been running in the Realms since it first hit the shelves and own pretty much every Realms product that has been published to date.
When I saw the plans of Silver Marches I was really disappointed. We had Waterdeep and the North, The Savage Frontier, The North, and Volo's Guid to the North already. Why did this place need revisiting?
Well, it seems it did need revisiting. The North has changed alot since those old products and Silver Marches does an excellent job of showing us those changes while offering a ton of adventure hooks and campaign style plots. There are even a couple of adventures in the book that seem top notch after a cursory look.
One of my other concerns was turning one of the great savage frontiers of Faerun into another overly civilized area.... this doesn't seem to be the case with Silver Marches. The cities of the march have banded together for common defense against the North's many and dangerous foes. The hint of danger still pervades the setting like it always has and you can add the political danger inherent in having two very stubborn loudmouth dwarven kings on the same council. The political structure is as much a danger as King Obould and his Orc Hordes... that is a welcome addition to the setting.
Apart from that the crunchy bits seem pretty good as well. Some neat new monsters along with some new Prestige Classes that work well with the setting but could also be converted to other campaigns...
Anyway... just my first thoughts after staying up and reading last night.
I'm not going to even respond to the comment about MoF being Munchkin... I hate that elitist and deragatory term. If you think there are power issues in the book, discuss them... but why paint the whole product with such a wide brush? Hrm.. I guess I did end up commenting
