I just submitted a game with the following score:
- Total score: 8821 points
- Normalized score: 5306 points
This was a quick game where I did not have an advanced strategy,
except building cottages in the early game, and farms at the end.
The main goal was to learn about the scoring formula and to study
the trade-off between technology and population.
My score breakdown is as follows:
3550 from Population (169/238)
1250 from Land (172/275)
3348 from Technology (504/301)
673 from Wonders (155/230)
Total Score = 8821
Score by winning this turn = 5306
First, I applied the scoring formulas in this thread:
http://forums.civfanatics.com/showpost.php?p=3354736&postcount=82
For a time victory, currentTurn=maxTurn, and all three formulas
simplify to:
score = factor*rawscore/maxScore
For the base score of 8821 I get an
exact match between the
formula and what is reported by CIV IV, provided that the score
of each component is truncated to an integer number, and without
applying the difficulty multiplier of 0,6.
For the normalized score of 5306, I get an
approximate match by
multiplying with the difficulty multiplier:
0,6 * 8821 = 5293
which is slightly less than the score of 5306 hat is reported by
CIV IV. Did I miss something here?
Second, I wanted to study the trade-off between population and
technology for maximizing the final score. On one hand one can
maximize the number of future technologies by leaving as many
towns as possible towards the end of the game. On the other hand,
one can maximize population by farming as many tiles as possible.
I asked myself the following question: If I convert one tile from
town to farm, how many population points do I gain, and how many
technology points do I loose?
Population:
I am assuming that all cities have reached their maximum population
limit by year 2050. With Biology, farming increases the number of
food resources by two, increasing the maximum number of citizens by
one. By applying the formula above, one citizen converts to 31 base
score points for this particular map. Equivalently, farming yields
31 population base score points per tile.
Technology:
To estimate the number of technology poins that are lost by destroying
a town, I make the following assumptions:
- The majority of technology points come from Future Technology
- Future technologies are researched during the last 100 turns of the game.
- The town is converted to a farm when starting to research the first future
technology.
- Financial leader (+1 commerce).
- Free speech (+2 commerce).
- Printing Press (+1 commerce).
- 100% research during the last 100 turns.
- Average of +150% research in each city from buildings/wonders.
With these assumptions, destroying the town costs:
(4+1+2+1)*100*(100%+150%) = 2000 bakers.
In my game, one future tech requires 5527 bakers. Furthermore, for
my map, the score formula results in 46 technology base score points
per future tech. This implies that the penalty per tile for loosing a town
can be estimated as:
46*2000/5527 = 17 technology base score points per tile.
To summarize, converting from towns to farms results in:
-An addition of 31 population points per tile.
-A reduction of 17 technology points per tile.
I know this is just an estimate, and there are complicating factors like
converting citizens into specialists. Anyway, the analysis suggests that
the game should end with a maximum number of farmed tiles. I believe it is
important though, to time the conversion from towns to farms to reach the
maximum population limit as close the year 2050 as possible. Otherwise
several turns with income from towns will be wasted.
How does this analysis agree with everyones game experience?
