I purchased the book and have found it pretty good. There are lots of interesting ideas in it, and I'm seriously considering a 7th Sea campaign.
There are lots of really cool feats...the fencing ones are particularly good (ie. parry, riposte, counterattack, etc.). Plus there are the unarmored defense rules, which are sorely lacking in the Core Rulebooks (big oversight on behalf of WotC). And I even think those rules are better done than the variants used by WotC for Star Wars and Wheel of Time. Sure, your characters get AC bonuses when armored, but they have to blow valuable feats to get them...
One of my favorites is more finesse. Basically, after you stick finess on your rapier, you get More Finesse on that blade too, and now your DEX score counts for dmg with that weapon, instead of STR. I think that more accurately represents the use of light fencing weapons.
The firearms rules are much needed, including feats for sharpshooting, piercing armor, etc. (builds upon the idea from 2nd Ed. that firearms are excellent against knights in armor).
Some of the core classes seem a little redundant....like the swashbuckler and musketeer, which are pretty similar. The main differences being that the musketeers get d10s vs. d6s, but the swashbucklers get more little abilities.
The setting is low magic, so they've made an assassin class, as a core class, with no spells.
There are rules for ships and mass combat, but oddly, there are no rules for canons. Those are offered for free on the official website (
www.7thsea.com).
The prestige classes are a mixed bag. Some are quite interesting, and others seem less necessary. But there are a whole swack of prestige classes that are 5 levels, and really help in customizing your character by having her follow a specific school of fighting.
There are some balance issues, and some editing problems, but overall, I found it a pretty good book, and a lot better than much other d20 stuff I've found on the market. And given that WotC really hasn't addressed swashbuckling games.....ever, I found it a much needed addition to the rules.
Is the book perfect? No. Is it pretty good, with stuff that can be used for a 7th Sea campaign, or mined for use in your own? I think so.
Does that help?
