Is effect cumulative?

Actually i'm pretty sure the Robotoid Factory and Mineral Scanner/Hybrid Farm thing/etc do stack... Or i've been misreading my Planet screens...

It works by ability. You get the effect of the best of each of the following abilities that affects a planet, regardless of what facility they are on:

Resource Gen Modifier Planet - Minerals
Resource Gen Modifier Planet - Organics
Resource Gen Modifier Planet - Radioactives
Resource Gen Modifier System - Minerals
Resource Gen Modifier System - Organics
Resource Gen Modifier System - Radioactives

Resource Gen Modifier Planet - Minerals and Resource Gen Modifier System - Minerals will stack with each other. But, two facilities that each have Resource Gen Modifier Planet - Minerals will not stack with each other.

Robotoids have 3 of the abilities, either planet or system. You can have a Robotoid Factory stack with a System Mineral Scanner, because one uses planet abilities, the other a system ability. But, a Robotoid Factory and a Mineral Scanner (both of the planet variety) will NOT stack their bonuses to minerals production, only the best value will be used.

oh....
so if I build an organic med lab and gestaion vats in the same system the reproduction is not gona stack?

[Fyron]

Nope. Only the best is applied. For facilities, most abilities that are percents do not stack. Actually, I don't think any of them stack... (for the same ability, System vs. Planet counts as different abilities, except for Happiness modifiers)

Does it mean, that System-wide happines modifier from facility and planet happines modifier from another facility won't stack?

[Roanon]

As system-wide and planetary modifiers are considered to be different, they DO stack. The same system-wide modifiers, even if from different facilities, are considered equal and only the best bonus is taken, so they do NOT stack. Same for planetary modifiers. For example, mineral scanners and robotic factories do not combine.
