Many thanks Geoschmo and Junkie - I love this board, 1 hour after posting two experts give me advice ... but raises other questions

:
- about TDM and DevNull : TDM is a super AI SEIV setting, DevNull has "real" gameplay changes - but what are the main ones ?
- And now I heard about P&N ... what has this one to offer ?
Many thanks Junkie for the settings file, is it usable with other mod/plain SE4 or only with P&N ?
BTW I was just browsing mine and figuring how to change the population modifiers ... Was thinking giving 1% per 10 M colonists, with reduced (by 10) pop growth rate !
I've also found a "min pop per facility" parameter at 50 (M I suppose), perhaps upping it up to 100 or even 250 can be a good idea.
Can I make my "RealEconomy mod" so easily ? Will the AI be able to manage the new settings ?
That'll be super cool !

Or perhaps I just have to play Proportions ...
And there is another thing that annoys me : the 300 M pop/transport (light !). This ruins the whole point of having slow colonial growth

, and I didn't find how to change that...
I want to have stg like 1000 to 5000 pop / KT cargo, instead of 1 M (that's a decrease !)
Where is the "weight of 1 population" parameter ?
Many thanks anyway !
