The main is that the marketplace is currently in its early stages, means that there is not as much content as in Unity Marketplace, this means that the price are high because you don’t have proper competition.
Give it time or expect the flooding of converted Unity packages into UE4 Marketplace to see the price drop.
Some of the items on the marketplace are quite amazing and the price is great ( UE4 arch scene is pretty amazing and the price is below the average cost ), while some of them ( character mostly ) are ridiculous…
I honestly would prefer to see the content used into some scene in detail, with a good understanding of what it can do and how it looks…I saw quite a lot of comments related to the poor quality of the asset, which is unfortunately something that you’ll find out after you bought it.
