Is it worth it to develop plugins for the marketplace?

Hello all, I know this is a bit of a open ended question, but I have a few ideas for marketplace content and plugins, but one thing I can’t help but notice is that there are tons of things available for sale on the store with zero reviews. This seems a bit discouraging since a lot of them look fairly high quality. It leads my to wonder if there’s really much of a market here or if it’s a case of too many products chasing too few customers… I obviously don’t expect any asset developers to get really specific on numbers or anything, but from the outside it really looks like the vast majority of stuff on the store is barely selling. Is it really as bad as it looks?
