Sledgehammer Games' Glen Schofield has seen the low user score and doesn't believe the bevy of zeroes that anti-fans have lined up seem paticularly fair. Via Twitter he asked for people with genuine opinions to step forward and leave a review:
"I don't usually do this but, if u like MW3 go 2 Metacritic.com & help our user score. It's suspiciously low. Be honest but help if u agree."
The message has since been deleted and, given some of the messages he's been getting, I'm not surprised. I can't imagine the user score is going to have too much of an effect on people wanting to buy the game, especially considering the critic's score is so high, but I still think anybody taking the time to mark it as a zero has far too much time on their hands.
