I started a new playthrough when phantom liberty released and I feel like I've had more game-breaking bugs than I did at launch. The ones I had at launch were mostly cosmetic, animation bugs, t-posing, Jackie eating his noodles with chopsticks that left a clone of themselves in the box, etc. This time I had to reload saves because, for example, Jackie just didn't get in my car at the start and so it never unlocked the controls so I was just stuck in a car forever.

That being said, the gameplay systems are massively improved, even if it still can be a bit buggy, and it's well worth a play. I just need to wait for mods to update for 2.1.
