I've tried unsuccessfully to find answers to these questions, so I'm asking here
(I'm not good in English, you can be a grammar nazi with me if you want lol)
1 - The attitude gain via the trade route can be stacked ? if I put 2 trade routes between the same 2 planets, will there be a greater gain of attitude than with just 1 trade route ?
2 - Race A has 2 planet (earth and mars) and race B has only 1 planet (Venus)
There is a trade route between Venus and Earth, and a trade route between Venus and Mars.
How will work the attitude gain ?
3 - Sometimes, I can't put a Trend on a planet. I have a message that say "This planet cannot have any trends right now."
Why is there a restriction, and how can we bypass it ?
4 - What are the factors that determines the price to paid to invite a race in the Federation ?
They are very fluctuating.
5 - what are the RCI values that determine the "Wellbeing admiration" between the races ?
