A more appropriate analogy might be if a team had created a "healthy foods" website listing some foods they liked and gone to the trouble of promoting it on places like HN and ProductHunt

Would it be reasonable to suggest that it'd be helpful if the creators of such a website went to slightly more effort to define the health benefits they were focused on and substantiate the claim that these foods were relatively healthy than someone creating a list of games they thought were fun on Steam? Would the value of the service lie in them doing that? I'd say yes
