Battlefield 1943 Breaks Sales Records, Sells More Than Bad Company
EA have revealed that with their release of Battlefield 1943 just a little over two weeks ago, they have created a monster. In two weeks they have sold 600,000 copies collectively between the Xbox Live Arcade and PlayStation Network - becoming the fastest selling day one and week one game on either platform.
In comparison, Battlefield: Bad Company was released to retail on the 23rd of June 2008 and also had a two week sales period. According to the NPD Sales numbers for that time, Bad Company sold 346,800 copies on the Xbox 360, and on the PS3 version sold less than 260,000 copies.
Therefore, Battlefield 1943 worldwide has sold more than Battlefield: Bad Company did in the US in the same period.
Magic: The Gathering Sells 170,000 in 5 Weeks
Wizards of the Coast, the people behind all Magic: The Gathering bits and pieces, have revealed that in 5 weeks, they have sold over 170,000 copies of Magic: The Gathering on Xbox live Arcade.
The trial version of the title has also been downloaded over 440,000 times, which we believe means the game had a 38% attach rate - very high considering what we expect from digital downloads.
The game is currently 5th in the Major Nelson Top 10, and has repeatedly beaten Castle Crashers since its release - a game that until now had never been outside the top 5.
We don't provide the 'easy to program for' console that they [developers] want, because 'easy to program for' means that anybody will be able to take advantage of pretty much what the hardware can do, so the question is what do you do for the rest of the nine and half years? It's a learning process. - SCEI president Kaz Hirai
It's a virus where you buy it and you play it with your friends and they're like, "Oh my God that's so cool, I'm gonna go buy it." So you stop playing it after two months, but they buy it and they stop playing it after two months but they've showed it to someone else who then go out and buy it and so on. Everyone I know bought one and nobody turns it on. - Epic Games president Mike Capps
We have a real culture of thrift. The goal that I had in bringing a lot of the packaged goods folks into Activision about 10 years ago was to take all the fun out of making video games. - Activision CEO Bobby Kotick
