I honestly haven't seen anyone write about 'how bug free' the games is.

Most of the praise I see usually revolves around it being a complete game, a big game, nonexistent microtransactions, the characters, the story, the freedom, even how pretty it is. But not that it's bug free.

Because it's definitely not without bugs. Hell, there's a lot of small details that could do with tune-up. And some got addressed in this patch. And I'm looking forward to Patch 2 as it's supposed to improve load-time, which would be very nice indeed.
