First of all Krastar, I've made a post during the summer called "All Economy Strategy". It's hell of alot longer than your tiny little post here. I'd also like to shamelessly advertise it here to you, asking you to go and read it. Even though I still play DA, the basic principle applies for bothe DL and TA. If you don't already know DL=Dread Lords, DA=Dark Avatar, and TA=Twilight of the Arnor. I'd love it if you comment on my post.
Second, I once was able to get a PQ 52 planet in DA. Which in that game is "impossible" without cheating or modding. Or so people say. Eitherway I don't have to prove myself to anyone. If I was in your shoes, I'd take that monster planet of yours and save the game a few times at that point. First save, to try out an all economy strategy (with a max population of 16-20 billion, a fertility clinic, a couple of entertainment buildings, and the rest stock markets). Second save, to try out an all labs aproach. Third save, to try an all factories approch. Fourth save, to try out a mixed approach (cultural buildings, factories, labs, markets, farms, etc. All mixed up on that planet). Fifth save, to try out your somewhat idiotic I must say Culture Bombing strategy. Yes we call it culture bombing too.
If you're going for the all economy approch. Put your Economical and Political Capitals on it. If your evil, put a Mind Control Center on it as well. First of all it gives you a 100% economic bonus, and second, it's good for your culture bombing strategy, because it causes all planets that are about to defect to your side, to defect almost imediately (1-3 turns is how long it takes I believe).
Case and point, having monster planets, is awsome.
If you cheat however and use the "PQ Booster" cheat on a planet before colonizing it (like a PQ 1-4), it is possible that it will have a hell of alot of Terraforming tiles on it. So when you use the PQ booster cheat (max PQ with cheat is class 36), along with that Biosphere Thingy, and your begining of the game ability of 10-20% PQ bonus, and the Good Ethics Paradise Tech. I'd bet that PQ 1-4 sucker can turn into an approximate PQ 60 powerhouse.
So ponder what I wrote here for awhile. For me the game has nothing to do with point scoring (even though I'm a member of an empire). I just play for fun.
So keep what I wrote here in mind the next time you decide to play (with or without cheats).
Till next time....................
(P.S.- In the smileys drop-down window, there is a "NEXT" option. It will take you to the classical smileys . Which are (I agree) less bizarre.)
