At its core, L5R hasn't chenged much since the 90s. All the good stuff is here. Roll and Keep mechanics, clan schools and techniques, combat and mass battle rules, etc. If you've played any previous edition, none of the mechanics will be a surprise to you. There's even details on the new Spider clan, if you're into that sort of thing.
The book is full-color glossy, and as gorgeous as you'd expect for a game that's been operating for over 20 years. Unfortunately, the pdf is atrociously bookmarked. Every bookmark is at a single level, and the list isn't collapsible. That makes navigating the book by bookmark unnecessarily lame. One star off for presentation, though the game itself is as solid as ever.
