Fantastic. It is much longer than anything before it (I've been playing since first edition LnL), but it is very comprehensive. It leaves very little for the reader to have to figure out on their own.
The manual is very well cross-referenced AND very redundant, the latter which helps with rules-retention and makes things easier to find during play (ie. "This paragraph talks about this rule, but where was that ONE line that pointed out this one exception that applied to this rule, etc etc").
Love the new Laying Smoke rules. It makes Laying smoke ever so slightly more efficient than before.
