I was wondering how compatible the two systems really are. Having been to the "long LOTR night" this week in my local cinema a was wondering of setting up an adventure where my player's come down to a planet that's a little bit like middle-earth. Would I be able to incorporate products like the Moria Box, that I would very much like to buy anyway *smile* with a little tinkering into my CodaTrek capaign or would the LOTR Core book it still be a must have?
