I just picked up a PDF copy and gave it a thorough read through and am compelled to say it is captures the essence of the original. You can even purchase a print version from Lulu. As soon as I get my copy from Lulu I will give a full review of the product.
Let me know in the comments if you would like to see some fan content for this game on the site!
Looking at these buildings I am seeing a lot of potential, especially when it comes to the roofs. You could use the a number of the Roof Molds (i.e. clay tile, wood shingle or slate shingle molds) available from Hirst Arts. If those don't peak your interest perhaps the O-Scale Weathered Gray Shakes from Scenic Express? Of course you could certainly keep it old school and simply cut out your own shingles...method one, method two, or thatching.
These are great looking buildings and with all of the bits you can get at places like Thomarillion you can create some truly stunning scenery while staying within your budget!
