I must say, the lovely cash buildup has been wonderful to have. We've been able to rush things all over the place, and the bribing has made things quite easy in some places.
I'd like to keep up the 60/40 as well. Aside from bribing, now we can try to rush some sewer systems/aqueducts in our cities. Mabye in a few turns we can do some serious celebrating and grow like mad.
We can also start more factory rushing as well as eventually offshore platforms. With such great production, rushing won't be as huge an issue and we can concentrate on pushing the science envelope.
I should have also mentioned that we DO have 9 entertainers that have been necessary in the empire. I still think that's not enough to require a boost in luxuries, but if someone else differs, I'd be happy to visit that discussion.
