1) Don't have any saves to check the description. Doesn't it say anything?

2) One with the flag is approval penalty from overcolonization, the other one is approval penalty from overpopulation.

3) - 0-10% Mutinous, minus 75% to Food and Influence generation.

    - 10-30% Unhappy, minus 50% to Food and Influence generation.

    - 30-70% Content

    - 70-90% Happy, extra 25% to Food and Influence generation.

    - 90-100% Ecstatic, extra 50% to Food and Influence generation.

4) Devoted and Loyal are approval levels on Empire scale. Same as Ecstatic and Happy, only Empire wide. Can be checked on Empire Screen.

1) Obelisk of Remembrance - This improvement offers 2 bonuses. Does anyone know if either/both apply empire wide, or just on the system it is constructed in?

Both effects are applied on the Colony where the Obelisk is built. :)

3) What are the exact break points for various levels of system happiness? Also is this documented anywhere?

Starmender is almost right. :) Those are the official values. :)

Mutinous - 0 to 15

Unhappy - 15 to 30

Content - 30 to 70

Happy - 70 to 85

Ecstatic - 85 to 100

I think all the other questions received satisfying answers thanks to Starmender.

addendum: if you're playing a dictatorship style government the approval level skips unhappy and just goes to mutinous at 0-30%

Thanks for the info folks.
