Agreed to the misuse thing but that can be avoided by moulding this idea to suit to the game environment, avoiding the drama and the possible abuse, it could be anonymous, must have a restriction on eligibility of reviewing and also to avoid any drama instead of reviews it should be like and unlike
Like and unlike would be acceptable in my opinion. However, I think we could benefit from comments if they were just optional? Like you could upvote or downvote, and then you have the option to say why or why not?
