This is a project I've been working on intermittently for the past two months. I downloaded a high resolution scan of the game board, tweaked the colors and noise, divided the rooms and corridors into tile sections and printed them out, glued everything to black foam core and here we are. The movement squares are all slightly larger than normal to allow wiggle room for furniture and doors, an issue my players were constantly complaining about.
I ended up with 12 corner pieces, 4 T-junctions, 6 6 square hallways, 8 5 square hallways, and two double width halls plus rooms. I'm really happy with the result, although the tiles could line up better. Modular the game adds an element of surprise as the players don't instantly know where on the game board they are, more flexiblity for custom scenarios, and I could do purely random layout generation like Warhammer Quest or Advanced Hero Quest.
