I think that there was absolutely no way to avoid controversy in this case, but I do agree that scores can generate specific amounts of disagreement more than anything in a review. This is not to say that scores do not work however, as that's really the bottom line for some people, no matter what you say. Leaving out a score may make some feel unsatisfied. If we were to make a change, I'd prefer something along the whole "Buy, Rent, Skip" system.
Regarding round-table reviews, I have always been for that type of system, as I think that there is nothing wrong with discussing a review with the team to look for any areas where things may have been considered too much, or not at all. There is nothing wrong with considering the reviews of others, such as Travis said, although you still have to avoid considering reviews which cannot, or should not be compared. In my eyes, a 3rd person shooter is different than a first person shooter, and a turn-based puzzle game is different than an RTS. Over-considering what you gave Lumines 2 when you score Soldier of Fortune 3 wouldn't make much sense.
One thing I do when I submit any work is ask if there is any feedback before publication, as I'm wide open to hearing opinions on my opinions and / or my score. In Kane and Lynch, even before this drama, my mind was fluctuating between the 7s and 8 level of scores. I create a sort of mental scale, where the good and the bad weigh up, and I go from there. I never said Kane and Lynch was a great game, but it's certainly not a bad game. Also, consider that almost all games are a one shot deal, even Call of Duty 4, in terms of single-player. While CoD may have had a 9.5 in single player and a 10 for multiplayer, the average was still somewhere between the two. Kane and Lynch had a 7.5 to 8.0 single player game, with an 8.0 multiplayer in my opinion.
Had Rob or Travis had a bone to pick with one of my reviews, I'd have no problem re-evaluating my own work to make sure that I considered everything possible. In the end though, an editors final score should be respected, even if an entire team thinks he's crazy. Sometimes EGM for example will have a mix of scores in their reviews that are so far off between the reviewers that you'd wonder if they were all playing the same game. That's just how it is though, editors are entitled to their opinions. Do you want honest reviews? If so, you have to respect the reviewers opinion.
Finally, I did mention a flaw like crashing, but I will say that with the Call of Duty 4 review, Rob had mentioned to me that there was a nasty multiplayer server bug that was going on during his play through. I experienced this myself for numerous days and nights, where it seemed the master server would crash and it'd be impossible to connect to a server and / or authenticate the validity of your key. Should this have significantly affected the score when it was something that we were all sure would be handled in a timely manner?
