Why is there no half star rating?

It seems like they give out way too many perfect scores. I'm not lamenting their reluctance to grade on a 1-10 point scale , but it seems they should and least add a half star. Don't you think?(I do actually read the reviews)

Because there are words underneath the stars. And those words will always tell a better review than any number you see.

well a 1-5 scale with halves is a 1-10 scale in a way

What's the Deal With Your Rating System?

Giant Bomb reviews games on a five-star scale that does not include half-stars. We feel that this benefits our reviews for a number of reasons. Five-star rating systems are a widely accepted standard outside the field of video games, from Amazon.com to The Source, and we feel that the pervasiveness of the five-star system makes it more intuitive for the reader.

It also helps avoid the hair-splitting that can occur within more granular rating systems. A score is designed to provide the most basic at-a-glance information about a game for those considering making a game purchase--it is not there to justify/attack anyone's entrenched position on the relative value of one video-game franchise, developer, publisher, or hardware manufacturer versus another. We include the full text of the review for those looking for more detail.

We do not use any algorithms to reach our final scores, relying instead on the experience of the reviewer. While fundamental issues such as graphical performance and gameplay originality will almost always be factors in determining a final score, it ultimately comes down to how worthwhile the reviewer found the whole experience to be. If that's not enough, here are some simple illustrations we think you'll find helpful:

While we don't believe any game is perfect, we recommend this game without reservation.

Still very good and easy to recommend, though it doesn't quite live up to its full potential.

The halfway point. An inherent appreciation of this game's specific gameplay style, characters, subject matter, and so on may play as big a role in your enjoyment as the actual quality of the game.

This game's problems outweigh its good qualities.

This game will make you wish you had died in a fire moments before turning it on.
