Notably, the PS4 version of Inquisition frequently froze, locking up the entire system and requiring a full reboot. In a few instances, this reboot process led to corrupted save files. According to representatives from EA, this issue is related to Sony's PlayStation Network 2.0 firmware, which has caused problems for other games on the console as well.
Near the end of the review process, Sony sent Polygon a PlayStation 4 that had an upcoming patch pre-installed ostensibly fixing the 2.0 problems. We played approximately 15 hours on this patched PlayStation 4 and did not experience any crashes. EA says this new PSN patch will be released prior to Dragon Age: Inquisition's release date.
