UK Charts: Gears of War Judgment hits top, Walking Dead in at third

[Nsanity]

This post from another forum pretty much sums it up:

"Gears 3 = 6 days of sales
  Gears J = 3 days

September release vs March release

10x less marketing, second team development. And even with 1/4 sales of Gears 3, Judgment took the 1 spot"
