I was browsing the psn store and obviously Sony have the new god of war advertised prominently. You click on it and it brings you to the deluxe edition for 69 euro. The standard edition costs 59 euro. So I was thinking gamestop in my country probably sell the regular edition for 70 or 75 euro and people clicking this link to buy it digital couldn't easily think the deluxe edition is the base game. It can actually be tricky to notice.
And the ratings suggest about 3 times as many have bought the standard edition which is quite a low ratio.
