Qwinn's Ultimate DAO Fixpack (thanks, PC Gamer), currently available on Nexus Mods, has taken on the unenviable task of addressing Origins' myriad of issues.
While this fan-made Dragon Age: Origins patch purports to fix an impressive 790 bugs in the PC version of the RPG, that's not even the best bit incredibly, it also restores a heap of hitherto hidden content that had been cut from BioWare's original release.
