The first thing that strikes you about Mouse Guard is the amazing artwork. The combined forces of the inked linework and the traditional-looking colours lend the book a quietly brooding atmosphere, infused with the colours of autumn. The pace of the story is easy, giving each scene the time that it needs to breath.
To say it's basically about mice with swords wouldn't do it justice (though it sounds pretty cool), because there's a fully realised world behind all that, with so much more to the mice way of life and the Mouse Guard themselves that it's more a story about comradery in the face of danger - the dangers faced by the companions who comprise the heroes of the tale to the greater dangers faced by the entirety of mousedom.
It's a tale with honour and heroism faced against dark deeds, but it's down to earth aswell and it's easy to care what happens to the mice.
The characters feel real and well rounded. The world also, with different mice exercising their different opinions on how to face the threats they all .. um ..face.
This has become a fond favourite and I can't wait for the next installment. In the meantime I'll have to content myself with the wealth of information about the world contained in the Mouse Guard RPG.
