How to plan a wargaming scenario?

[Weasel]

I am not referring to any specific wargame here, instead I am looking for a generic answer.

In a scenario editor, typically you create a map, set the objectives and give points values to the objectives.

Then you create units and give points values to the units.
Then you create victory levels based on points ( or what ever).

1. Where can I get the imagination from to make a scenario?
2. Is there a mathematical formula I can use to apply points values to units and objectives?

Wow, that is a loaded question. I try to base my scenarios on real life battles, at least for the ground work. I will then transform them into something original or else the players will know exactly what to expect and such. Then you must play test them, over and over and over; too many times I have played tournament scenarios where they have not been tested and have showed it.

Values for winning is largely dependent on the game engine. In Steel Panthers a meeting engagement is normally 1:1 for points and 2:1 for assaults. In combat mission it ranges from 1.25 to 3:1 (I think), so picking a ratio is once again dependent on the game and play testing.

For objectives I try to make them realistic and real world. Often the game will stick a flag out in the middle of a field and ignore the crossroads in the town, doesn't make sense. So try to place the objectives where they would make sense in the real world. I try, for the most part, not to make games dependent on total unit losses as that takes away from a country that largely didn't care about them.

I think the biggest thing is you have to play test, even if you fight against yourself of let the computer fight itself.
