I set the min = 0 and max = 1 for testing purposes last night, and as far as I can tell it made already established pirate bases disappear.
max=1 causes disappear. I mean, there was more than 1 and some gone.
And yes,
min is actually do something if
increased.
min=3
max=10 will give you lot of unforgettable feelings.
"raidCooldownDays":1,
That string is a delay related to player(and possibly AI) raiding a planet. If set to 0 - you can raid a planet as many time as you wanted without any waiting. Increasing will make you wait more. Does not directly related to pirate raid spawn frequency or else.
It's very noticeable because of the rapid succession of pirate raids, and they depend on existing bases.
It is not
very noticeable actually. Pirate base can spawn next day the last was destroyed on min=0. It is very rare not to have any base longer than two month even if
min=0. Some kind of random or unknown correlation. And the raid succession does not directly related to base quantity, rather to their size (stronger raids). So next string can actually help more:
"pirateBaseMinMonthsForNextTier":6,
However, last was not heavily tested. Rather theory.
