Come on, let's put this in perspective... In Itch's current system, you can rate games without commenting. This doesn't help at all. It allows rating spamming without the player even needing to explain the reason for their rating.
That is, if there are reasons at all, and it's not just a grumpy player saying "I didn't like the content, 1 star."
For Christ's sake, guys. This isn't serious... It's amateurish for an old site like this.
So seriously, my deep desire is, in order to rate a game, the players needing to leave a full comment on WHAT ARE THE REASONS for the good or bad rating.
It might be a pain to moderate thousands of comments, but it's simply unfair to the devs to leave them vulnerable to this kind of thing due to poor/limited moderation.
