MG vs. TB conflict mechanics

I’m sure this has been asked, but I couldn’t find any thread…

Are the TB conflict mechanics considered an official update to MG? Or, do the MG Conflict mechanics stand alone?

If it’s the former, is it a complete replacement?

Cheers!

They remain two separate games. I think you could play Mouse Guard with the Torchbearer conflict rules pretty easily, but it was not the intent to replace the Mouse Guard rules.

Just what I needed to know. Thanks!
