Yeah- but the feel of the game I guess... I mean having never read the comics I think I'd be mainly influenced by things like Secret of NIMH, and my own imagination.
Like, I have no idea if say... Owls can talk in Mouseguard, but in mine they would.
Really I was overstating the canon problem- if I told my friends I have no idea what the actual comic is like, but I have X idea they'd be cool with it... Most of them at least.
I guess I'm not sure I'd like to get someone's hopes up if they're a fan of Mouseguard only to have them actually play something that has nothing really to do with Mouseguard the comic whatsoever. If that makes any sense.
Actually, I think it's more based on Redwall (and Watership Down) than Secret of NIMH.
I've only read the first four comics, and I don't recall seeing the other animals talk, though it may be a case they have different languages (kinda like Keehar in Watership Down).
By the way, the first two adventures in the rulebook are straight out of the comic's first couple of stories. It should be pretty easy to follow canon if you want. With that said, I think you can go quite far out of canon and you should be okay - there's a lot of directions you can take the game.
