I agree, go for it! You're as entitled to your opinion as anyone.
HOWEVER: If you're going to rate games, take a few minutes to write a paragraph or two about the gameplay -- what to shoot for, how to score points, where the ball drains if you're not careful, that kind of thing. I couldn't care less about a numerical rating but I often get very interested in other people's gameplay descriptions, because I didn't grow up on these games and they can't be played just anywhere. A few words of description also gives some context for what you like and don't like.
