Give me a practical model. Or, at least, describe what you mean by
"count", "cumulative_score" and where "want" comes from.
Here is what I thought of:
1. Each time a city decides to go for an aggressive unit, the barracks want
should be bumped up. This barrack want should accumulate, the simplest model is
new_want = old_want * INFLATION_COEFF + increment
2. It should be adjusted according to the production (even better -- potential
production) of the city and how it compares to the national average -- here is
an opportunity to softly introduce barrack quota.
3. The barrack want should overspill into the SUN_TZU want.
4. The want should compete against other similar wants (and tuning it is the
Ross, if you want to make a patch for this or any other model you think up,
please do so. I will work on it with you, but you must take it easy and
(a) not refer me to the corecleanups :)
(b) try to make the changes localised -- it makes it easier to read and easier
to find time for.
