High difficulty means two things:
1) Population is less efficient an investment. The increased maintenance is mostly keyed off population, so the marginal benefit of each pop point is smaller. This means alternate investments are comparatively better: Pyramids, GLH, Currency, Courthouses, wonders in general, multiplier buildings in a few key large cities... but also cottages. Cottages' growth rate doesn't change while the rate of return on population growth (think farms) is lessened!
2) Techs are more expensive. This means that early game will be more tech-constrained than usual (which is a vote against early religion and thus to some extent in favor of creative and against spiritual). It also means that bulbing before the renaissance is less wasteful.
High difficulty / toroidal sure seems like a nerf to expansive, but I'm not convinced it makes financial any worse.
