A well-realized world with a lot of opportunities for a variety of adventures, from political intrigue to epic battles.
One of the best things is that the rune stryders do not overshadow the game as one would expect; while powerful, they really require the cooperation of the whole team, so GMs aren't forced to split up parties or have a bunch of bored players while the "pilot" does his thing.
The only real drawback is that the file is locked, and there is a few major errata that comes seperate. I would have preferred an unlocked file and change-pages.
But overall a good product and worth the money.
