that's good, other wise that would be a very EZ exploit....
Not really. How do you figure that, then?
All planets should have a base PQ and a current PQ. So, for a planet with a base PQ of ten, and a civ with a PQ bonus of 10%, the base PQ is 10 and the current PQ is 11. So if the same civ abandons this planet, it's current PQ goes from 11 back to 10. If the same civ then colonies that planet again, it's current PQ goes from 10 back to 11. Where's the exploit in that?
It makes no sense to me that an abandoned planet LOSES PQ points. If anything, in many situations, you might expect the quality of an given planet/ecosystem to RISE without the interference of billions of citizens! Consider what earth might be like today had humans not evolved. I think its PQ would be just a LITTLE BIT higher, eh? But no doubt George Bush loving, SUV owning Americans would vehemently disagree.
Sounds like a bug to me.
(And remember, the original poster is spending HALF his race ability points for a +20% bonus, so of course, he's keeping a eye on when that bonus is applied!)
