Rub the wizard! You should probably wash your hands.
1976 Orange edition. Appears to be a pretty fun book for its time. Although I have only read it, not played it.
It is an interesting read:
oddly staggered rules (needs a reformatting)
lack of clarity (editing)
inconsistent use of terminology!
no scenario suggestions
assumes the reader has a familiarity with the wargaming world of the time, e.g. averaging dice, the actual phases of the game are fuzzy, the interpretation of the crt's, figures and their actual points/scale, use of order sheets, it is SORELY lacking in examples of any kind, no errata sheet.
Therefore, even though the rules are not complex as a whole, a newcomer should avoid them. Hell, I should probably avoid them.
It does have pretty interesting flavor detail when it's all taken in. I have a lot of fun playing old rule sets for nostalgia's sake so I look forward to trying it sometime.
UPDATE: If anyone has deciphered these rules with regards to units/points/figure points/models let me know your interpretation.
