Population growth increase proposal.

#1 Post by Daybreak »

Thanks Oberlus for the population formula you gave me in another post.

When population < maximum, population of next turn will grow by
population * 0.08 (or 0.12 with policy Population) * ( 1 + (1-population)/maximum )

So I wondered how long it took to reach max population of a planet- here are the calculations

Currently (Dont know why the table and tbody appear
[tbody] [/tbody]
Max Population Turns Taken 0.08 Without Population Policy Turns Taken 0.12 With Population Policy
10 53 35
15 64 43
20 72 48
25 78 52
30 83 55

I thought wow - I believe that is too long. A quarter of the game could be gone before some planets are fully populated, and it puts so much more emphasis on having population growth.

So I decided to try this formula

When population < maximum, population of next turn will grow by
population * 0.12 (or 0.18 with policy Population) * ( 1 + (1-population)/maximum )

The results -
[tbody] [/tbody]
Max Population Turns Taken 0.12 Without Population Policy Turns Taken 0.18 With Population Policy
10 35 24
15 43 29
20 48 32
25 52 35
30 55 37
I believe this is a lot better. Its not to long, but it is not too short as well.

Thoughts?

Actually the value has lately been increased half the way to your suggestion.

I am playing MP 20, so it looks like it is updated in newer versions, I have not played.

So we now have this

When population < maximum, population of next turn will grow by
population * 0.10 (or 0.15 with policy Population) * ( 1 + (1-population)/maximum )

Max Population Turns Taken 0.10 Without Population Policy Turns Taken 0.15 With Population Policy
10 42 28
15 51 34
20 58 39
25 62 42
30 66 44

I think it still looks a little slow, but at least it is better.

What's the normal duration of a game then? If 50 is a quarter, 200 turns? He.

I think it is OK as it is.

maximum population is not really meaningful/interesting - as growth in the end is really slow and derived production usually scales in a linear way.

fast growth happens up to 50% of maximum population. Somewhere between 50% and 100% there is a sweet spot until which growth on a planet really matters (in the sense that waiting for the last few percent is not worth it so much).

could you have a look/do a table how long it takes to get to e.g. 80% (or 90%) of max pop?

at 80%

At current rate
80% of Max Population Turns Taken 0.08 Without Population Policy Turns Taken 0.12 With Population Policy
10 38 26
15 46 31
20 51 34
25 54 37
30 57 39


at the proposed rate - not sure if implemented

80% of Max Population Turns Taken 0.10 Without Population Policy Turns Taken 0.15 With Population Policy
10 31 21
15 37 25
20 41 28
25 44 30
30 46 31
