BioWare Points are essentially a PC version of the Microsoft Points that used to serve as the virtual currency on Xbox Live. If you want DLC for the PC version of Mass Effect or Dragon Age, you purchase BioWare Points and then use that to buy the content online. That won't be the case for Dragon Age: Inquisition, however, or for any other BioWare game in the future.
"Based on user feedback, beginning with Dragon Age: Inquisition, BioWare Points will no longer be supported as a means to purchase DLC," BioWare announced today. "This applies to PC or Mac only, as consoles will continue to support their respective methods of purchasing downloadable content."
So exactly how will you go about purchasing the inevitable DLC, you ask? "Instead of using BioWare Points, PC and Mac users can purchase future DLC directly through Origin, using currency," the announcement says. Games that currently support BioWare Points for DLC purchases—Dragon Age: Origins, Dragon Age 2, Mass Effect 2 and 3—will continue to do so.
