So, since population science & some policy cards have been nerfed, alternative sources of science become more interesting. I experimented a little with just growing my cities - building granaries & aquaeducts instead of campuses & using the additional population to work ziggurats. It seems to work quite nicely, it allows you to concentrate on beelining military units. Because of the city state/adjacency bonuses this might also be combined with a few well placed campuses. But it seems like a steep investment. Just wanted to ask whether someone tried a similar approach?
