You know how rare it is for a game to actually get 1 m+ first week right? It only happens like once or twice a year if we're lucky.
So no, no sane people expected 1m+ first week.
Odd. I could have sworn there were more than 2 games that sold 1M first week in 2008.
GTA IV 360 - 3.4M
SSB Brawl - 2.8M
GTA IV Ps3 - 2.5M
Mario Kart - 2.4M
Gears 2 - 2.1M
MGS 4 - 1.7M
Wii Fit - 1.4M (Japan launch was in 07)
I'm sure I'm missing some, and I'm not even counting multiplats.
And in 07, there were even more.
I'm guessing that the average over 5 years, would be 1 1M+ seller first week a month.
Oh, you meant worldwide.
It's still not very common for new IPs to pop up and sell 1 m+.
And it's also not common for new IPs to get the sheer amount of hype that Little Big Planet has. And it's not like it was just a hype machine right at launch time. It's been garnering a ton of hype for well over a year or more now.
Into week 3, it's painfully obvious that LBPs production does not live up to the hype. It may even be the Derrick Coleman of video games. Mario Kart sold 90k (US) plus last week - in its 29th week. That's legs. Comparably, Fallout 3, a farily hardcore RPG sold 2 times as much as LBP and I would venture to get it didn't get nearly the advertising budget.
So a game selling < 40k in week 3 - with this type of build-up - is very poor.
Some of you die hards may not be discouraged, but I guarantee you the developers and publishers are a little bummed out over these numbers.
