The current rating scheme is a simple five-point system: 5 (Excellent), 4 (Good), 3 (OK), 2 (Poor), and 1 (Bad). If it helps, there can be a virtual 6 (Perfect) and 0 (Unredeemable).

The images used for each are:

Excellent

An excellent experience, one of the best of its genre.

Good

A good experience, however flaws prevent it from receiving the highest ranking.

OK

While not accessible to all, something ranked OK will likely appeal to people in its niche.

Poor

While not completely worthless, severe flaws prevent it from scoring higher.

Bad

The worst, not worth having for any reason.
