Not under all circumstances, no. I was in no way blocked from playing it on a brand new PS4 that was never connected to internet. However I pretty reliably experienced, after leaving the PS4 to sleep for longer than 1-2 days, a severe input glitch when I resumed the game. To fix the glitch I had to restart the PS4 and game, which takes more than 5 minutes. Later I plugged in the internet and the glitch never happened again. I never made the connection between the glitch and DRM, but it seems likely to me now that they are related. I had assumed the glitch was a known bug that the developers were disincentivized to fix because they want the internet connected for telemetry.
