BioWare makes really good games, and people love them enough to actually purchase them in stores, is there really anything else to say?
If BioWare's epic RPG didn't sell a buttload, that'd actually be news. Regardless, the world should know that Dragon Age: Origins has sold over 3.2 million copies worldwide. This is according to internal EA data, which also claims that Madden is part of a healthy child's education, so take it with a grain of salt.
Seriously though, there's no reason to doubt this announcement. Dragon Age: Origins is a great game, and its developers pulled off creating a different kind of fantasy world that doesn't plop in the same orcs and goblins we've seen before. I'm not sure the world Dragon Age takes place in has ever been named (though if it has I would be interested to find out), but it's rife with lore and is as deep as fantasy worlds come. This is evident in the constant stream of Dragon Age DLC that has already hit us, with a full retail expansion, Dragon Age: Origins - Awakening, scheduled for release on March 16.
According to EA's press release, this makes the sixth major blockbuster BioWare has released in a row, following Baldur's Gate (still my favorite), Neverwinter Nights, Star Wars: Knights of the Old Republic, Jade Empire, and Mass Effect. I'm not sure why EA didn't list Mass Effect 2 amongst those properties, as the company revealed in late January that it sold 2 million copies in its first week, which puts it in even higher standings than Dragon Age. Maybe EA doesn't consider a game a blockbuster unless it goes triple plat, yo.
