According to some information released in their latest financial report, EA revealed that Dragon Age: Inquisition was the most successful launch in the history of BioWare. Ever. Period.
Dragon Age: Inquisition captivated fans and critics worldwide and it quickly became the most successful launch in BioWare history in addition to being named to more than 200 “Game of the Year” lists. The single player campaign alone has been enjoyed for more than 113 million hours.

Blake Jorgensen noted the milestone during their call to shareholders.
"In particular, Dragon Age: Inquisition had by far the most successful launch in BioWare’s history, exceeding our expectations. In addition, game sales for last-generation consoles were also much stronger than we had anticipated."

It's a well deserved success as it was easily one of my favorite releases of 2014.
