It's very simple, plays quickly, and will cater to two – eight players.
I couldn't find a copy locally, so I thought I might as well make a set of my own. This is (almost) it — I still have to make the layout grid (the work of a moment, hopefully) and find something to use as player markers... probably painted chess pawns or the like.
The tiles are 50mm squares of 3mm MDF, lovingly painted by yours truly. I could probably have done them more neatly, but these will serve quite well I think. The blank one in the bottom-right corner isn't used in the game layout; it's a marker tile which indicates who gets the next draw of the tiles. In the proper game it has a dragon printed on it; I've just painted mine metallic gold.
I think, if I were to do it again, I'd bump up the tile size to 75 or 80 mm square, and maybe do them in stained oak or something, with the tracks outlined in pyrogravure.
