i do not know if anyone other than me uses this method to win games do
it right and you could get over 60000 points and its not cheating i am
a very bad player myself i used to get 25000 to 35000 whith this method 3 days ago i
found out how to double that score to get over 60000 but it does take
slightly longer anyway i have been talking for to long lets get on with
this...
First of all set it to theas settings i used the immense map ok tern off
research alliance influence and ascension victory
and set the settings to what you see in this pic

ok next chouse a Race its best tou use a custom Race with the super diplomat abilaty as seen bellow

Next change the dificulty to suicidal and your opponents relations to friendly see here

Next
this is very important its best to use custom Races so you can change
there ethical alignment to the same as yours also change the aggression
to peaceful see here

now start your game and wait until you are allies with all other players

Then research all cultural tecs starting from xeno business up to cultural conquest

Then
build constructors and send them to your opponents planets and and have
them build influence starbases it some times takes more than one



now wait until you see this

Eventaly they will rebell and join you


do this with every one of your opponents planets
