Yeah, I hear what you're saying OmikronWarrior. Growth does seem to be a good money-maker judging by your numbers. It's just, if you took Growth instead of Order intending to make money on it, it's like you're saying "I'm going to survive for 100 turns and then I'll really cash in!"
I don't think you can always assume you're going to survive that long..
It just seems worth it to take Order and get the money in the short run and use that money to buy troops to expand to get more money. But, maybe a Growth-3 defensive strategy, possibly combined with clamming or bloodstones, with the intent of being peaceful and just hoarding the wealth, could be viable.
