Well in this topic specifically Danyjel seemed concerned about objectivity vs subjectivity. But anyway, I agree with Fquist. Short reviews should be allowed, but detailed ones should be encouraged. J2Ov2 will have a system to encourage detailed reviews.

As for ratings, there are two types: objective and subjective. A level can be rated for its technical merit, or simply how much fun it was to play. Anybody who has played the level could come up with a rating for it. The current system in J2O though is that ratings can only be given if supported by a review.

My thought is that a rating can be just how much someone likes a level. After all, people make levels so that other people can play and enjoy them. How good a level is technically is related to how enjoyable it is, but not directly correlated. Most people use "Will I like this level" as their primary criterion for deciding whether to download it. Allowing ratings based on how much someone liked a level would be a better guide to potential downloaders than ratings based on technicalities. It would also encourage more people to rate levels, giving a more accurate average rating. Using J2Ov2's encouragement system, a secondary average rating could be calculated only from detailed\objective reviews.
