Just a quick plug for a new product. John Graham-Leigh, Society of Ancients stalwart and accomplished wargamer, has just had a booklet of his simple solo/multiplayer campaigns released by the SoA. I've seen the PDF draft and intend to pick up the booklet.
It looks like it will be a good addition to the library. More info on the SoA blog here (which I also wrote, just to be clear, transparent, above board and so on!).
