US games sales down 17% in April, second monthly drop. http://www.reuters.com/article/technologyNews/idUSTRE54E03D20090515 Not as bad as it sounds as last year we had two big sellers at this time(GTA & Mario Kart), and big sellers (whatever they are, are still to come). 800k DS sales in April. Interesting reading...
I would say those numbers are very good considering the economic climate. I read a report that said Japan's entire exports were down 49% from April of 2008!!!
The entertainment industry usually does well (relatively) during economic downturn. Lots of people escaping reality and such.
I actually think they take a huge hit. Parts of it, anyway. Used shops do well, new retailers do bad (for obvious reasons). Torrent sites benefit this most.
