The new set looks like it's an interesting idea, allowing players to (more or less) pick and choose which buildings they want to collect and place in their cities while still getting max effect from each. Previous sets have more or less required you to collect the whole thing in order to get all (or the best) bonuses, so it's nice to have something a lot more modular, and as always the art of the buildings looks great (I'm assuming most if not all of them are animated as well).
That being said, I'm personally not a fan of it. As others have pointed out, the small buildings and overall small effects means that individually these buildings are all rather weak, and it's more effective to collect things like Tribal Squares if you're interested in goods, or the classic SoK if you're interested in FP. The individual impact of each of these buildings is very low, especially if the intention is for these tiny buildings to take spotlight as daily specials.
