The November Videogame Market By the Numbers
Along with the news that more than half of the US is playing games, the November NPD numbers offer an interesting insight into the games industry. The ongoing console war was white hot, with record hardware sales. The Wii outsold the PS3 by half a million systems last month, and is quickly gaining on the Xbox 360's total sales figures. The big winners last month were software publishers, though, with a record $1.3 billion in sales. "Obviously Call of Duty 4 performed well on both the Xbox 360 and the PlayStation 3. It is now second only to Halo 3 for first-month sales numbers on the Xbox 360. On the PlayStation 3 no other game has launched as well as Call of Duty 4 in November. Super Mario Galaxy performed extremely well for its first month. Two new properties - Assassin's Creed and Mass Effect - sold well enough to make the top 10. Across both platforms, Assassin's Creed was actually the second best selling game of the month. It is amusing to note that despite the unprecedented Nintendo DS and PSP sales, no game for either system sold well enough to make the top 10 software list for November."
OK, I think I've got it.
Let "certain group"="the people claiming Nintendo is manufacturing this shortage"
Then the sentence was "You can only wonder how many systems certain group think are being produced."
I think the better way to state the sentence would have been: "You can only wonder how many systems are thought to have been produced, by the people claiming Nintendo is manufacturing this shortage.".
May the Maths Be with you!
