First of all, a good review is not one that gives a game a good score, but one that gives an unbiased, accurate score.
Brink can have the best gameplay, the best customization, the best maps, but if it comes with bugs that make it unplayable, then it can't get a good score. As said by the reviewer, Brink is based on multiplyer, and since this game has a major flaw in lag, then it can't have a high score. Now, add the terrible issue with the graphics, and the fact that they decided to make a game based on teamplay (witch can be better achieved with friends) and not include some sort of lobby system...this has to be the dumbest and most frustrating idea I have ever seen.
