Yes, comment always make people happy... then why aren't comments and reviews the same thing? When I review a game the prompt asks me how many stars I want to give it and to leave a review. But that review won't be published in the comment section, which penalises the developer as they won't receive publicity for it. Of course I could leave a comment instead, but why then is the system asking me to leave a review? That's the core of the discrepancy for me, as a user that wants to support small creators.
