Killzone 2 require "good" marketing more than good reviews for great sales

I ll give you one instance to show how important the ad really is:

LBP was heavily advertised in UK 2 week after it launched(at first it didn't do good ,,,so they decided they need heavy ad campaign for that game)

LBP cracked 350,000 units in UK in 2 months(more than MGS4 in 8 months)
