[单项选择]Many video games feature an invincibility power-up
that makes the players impervious to damage, at least for a while. As the
economic crisis hit in late 2008, some said the same about the industry
itself. The theory went that sales of video games, which had been strong
in 2008, would also be strong in 2009, because games are a relatively cheap form
of entertainment that let people escape from gloomy economic reality.
At first glance the sales figures seem to debunk the idea that video
games are recession-proof. In June 2009, for example, sales of games in America
were 31% lower than in June 2008, according to NPD, a market-research firm. In
July sales were down 26% , the fifth successive monthly decline. But the
year ended with a record-breaking December, as people bought consoles and games
for Christmas. Globally, says Piers Harding-Rolls of Screen Digest, a
consuhancy, sales of games were down by 6.3% in 2009. The number of Nintendo Win
and Microsoft Xbox 360 consoles sold was flat in 2009 ; sales of Sow’s
PlayStation 3 were up by 22% after a price cut.
In some
respects, this stumble reflects gaming’s new popularity. When it was less of a
mainstream activity it was not so connected to the wider economic cycle. The
success of the family-friendly Wii has broadened gaming’s appeal, but the new
players it has attracted are less fanatical garners who are more likely to cut
back in hard times. During 2009 more people turned to mobile, web-based or
second-hand games, says Mr Harding-Rofls.
Another way of
looking at things, however, is to say that spending on gaming is driven by big
hits, and that the slight decline in 2009 reflects creative rather than economic
weakness. Entertainment industries always have their ups and downs, says Shigeru
Miyamoto, the creative force behind many of Nintendo’s biggest games. There was
an unusually large number of hits in 2008, which boosted sales, and fewer big
releases in 2009 until late in the year, which may explain the weak mid-year
sales. The biggest hit was "Modern Warfare 2", released in November, which
became the fastest-selling game in history, selling 7 million copies worldwide
on its first day. The top 20 games took a larger share of sales in 2009 than in
2008, which shows that the games industry is becoming increasingly polarised
between hits and misses. Hence the hit-and-miss results of the big publishers of
video games.
Overall, says Mr Miyamoto, 2009’s crop of games
may just have been less compelling. "We were not able to produce fun-enough
products," he says. That highlights the importance of continued innovation, he
says—but it leaves unanswered the question of whether gaming is indeed
recession-proof.From the fourth paragraph, we can know that______.
A. entertainment have been in the slight decline recently
B. creative games will bring good sales
C. sale increasing by the end of 2009 is due to big hits of games
D. "Modern Warfare 2" benefits from the Shigeru Miyamoto’s
innovations
