Yeah. In a play test with this sucker I upped the chance to 90%, and over half of the worlds were War Torn. Made for a very interesting play test to say the least. Hear us DEVs...We want the option.
Ha, sounds like fun. Must have been some kind of Galaxy-wide conflict, other than the one the TEC, Vasari, and Advent are waging.

There is a way to increase the chance of getting a certain bonus rather than the others, once a planet has been assigned to have a bonus. During preliminary testing, I put more than one 'Hollow Core' in the 'available' bonuses list for the Asteroid planet type, and it seemed to pick that one more often, which makes sense.
And there is a way to force certain planet types to have a bonus, like Pirate Bases, they will always have the 'Loot' bonus. But there's no way to randomise it. I hope we get the option, it would be very nice.
If you ever have any ideas for new ones, just let me know

Thanks again for the feedback.
