Men at Arms is a set of one-brain-cell rules from the fertile brain of Jim Wallman. Jim writes:
These are rules for playing a wargame with toy soldiers. It is intended for several players – say 4 or more. Players control significant leaders – the key lords or knights, who in turn have contingents of fighters under them. Why �One Brain Cell�? Well, many sets of wargame rules these days are horrendously complicated, with big thick rule books to read, dozens of additional books to get (at unreasonable expense) and exceptionally complicated rule mechanisms that take ages to work out. My brain is too simple for this, so I tend to write rules that one require a single brain cell to use and understand. This tends to make games easy to learn and play, and, amazingly, are just as much fun as the dense and complicated game rules for which you have to pay a King�s ransom. Odd, isn�t it?
