A lot of the hate was undeserved, IMO. Besides one absolutely hilarious bug where I called my ride in an odd place, and another where part of a mission didn’t trigger so I had to reload the last Autosave which was about 30 seconds back, the game ran well for me and a lot of friends at launch. And CDPR responded quickly and had patches out within a week fixing most of the gameplay affecting bugs.
I typically judge games pretty harshly, and my only experience with CDPR prior was Witcher 3, which dropped with some bugs but was patched within a week, and really didn’t understand the level of shade CDPR received.
