If by scale you mean figure size then they are written for 15mm but can be tweeked very easily for other sizes. If you mean number of figures then it is up to you. The better your troops the more they cost and so the fewer figures you need, e.g. a unit of highly trained veteran mercenaries (to include Richard Burton, Roger Moore etc.) would be a few figures but a mass or mob of poorly armed rebels will involve more castings. I recomend you buy a copy (should be able to get one cheaply on the old e-bay. There are two editions, either will do) I like the little 'chrome' things like: Dicing up your county's name & flag; Political flow charts for the different army types (popular front, superpower backed, colonyist, religeous leader etc.); partially hidden objectives (you know what 3 things the enemy wants but not which one is the big points/ middle points/ low points); The variable number of moves (at the end of each move defender throws a D6 & takes that of the 'clock' i.e.32 points. So for example if there are 6 points remaining the game might end this move, if the defender throws 6 at the end of the move or it could go on for 6 more moves if he throws ones each time. Hope this is of some use.
