race traits

Emotionless trait will prevent civil disorder;

Example; Some alien species is in one of your systems with 40 ships; and you can't reach 'm
Your planets start revolting. All production will stop because of the revolt.

See my frustration?

However; a bad effect is that you also can't get jubilant, which would increase growth.

As there is only 1 happiness table, at present your people grow unhappy when you declare war even if your entire race is geared towards a Psycho Warrior race. Emotionless can save you from having to quell your own empire when you declare war on everything in sight. Otherwise it's a long task of having to build fighters and ships all over the place just to placate your people.

Playing Touhou games (Go here if interested . No, nobody else is that good/insane as that replay). No rush for SE V bug fixing.

Emotionless does have a down side in that I think it stops the positive effects of happiness. A naturaly happy warrior culture with several levels of sociology is my preference
