If you put a product review system similar to what is currently used on the Unreal Marketplace, people will try to bypass it.
If you put a system to increase top rated products visibility, people will try to bypass it.
If you put a seller reputation system, people will try to bypass it.
If you put a system to increase top rated seller visibility, people will try to bypass it.
The quality of a product should matter the most. If Epic keeps the system simple, it can be fair for everyone. In this way, sellers who have a higher number of products and maintain a better quality will likely sell more, and success will not be determined by who can bypass the systems.
