Potential patch idea....

Good ideas, indeed!

Well occuping does have -long term- financial reward by taxing. Now, I totally agree that with extermination some buldings go down as well. Sacking would be a better term.

Well, exterminating has to be akin to razing/sacking, I mean the citizens won't line up nice and orderly for you to kill. I'd imagine lots of burning/pillaging and the like is done. This does sound good though, Occupy and loots nets most cash, Enslaving nets half that, and Exterminating gives barely any.

Theres also a good method you could use as to what buildings would get damaged. Have it so any buildings normally requiring a higher level of pop are damaged to 99%, that way theres alot spent in repairs if they do it. Exterminating should be the exception when conquering, not the rule as it is now. This could be potentially unbalancing if a player ran around doing it to AI and abandoning regions, but then again theres lots of exploits people can choose wether or not to use.
