Sorry about that.
I didn't want to suggest to you to change their default culture in files but was nearly suggesting to all the people that use my cultures mod (not everyone has to or will, of course) to make them conquerors.
Of course, if you change their default culture to conquerors all people would HAVE to use my mod when playing with this race, and that wouldn't be right.
When I was making conquerors culture I was aiming it to be used by races that would be a huge threat the entire galaxy (something like default MEE, only this time literally Mega Evil). So far I haven't found any race competent enough and with right RP model to use this culture. This is where Pyrochette kick in. They have all the stuff needed for it.
All I know I will use them in every game I play.
