I haven't encountered the death mechanics yet, but the save anywhere thing sure is nice.
We talked about this yesterday, but having spent more time, I can appreciate your frustration with the camera but honestly can't say I've had that problem. You can hear enemies spawning, and all you have to do to spin around is press back and hit the B button.
Quest-wise, the system is weird. I don't really like it. It strikes me that they did it because they were like 'OH WE ARE ON A HANDHELD SO WE MUST MAKE BITESIZE.' I haven't had any real issues with it, but I still think it makes the game feel more compartmentalized than it does.
And I don't mind the AI, but she is incredibly chatty and doesn't really... add anything to the conversation.
Overall, I'm enjoying it. It's way easier than earlier games in the series, which I don't like, but I also don't expect everyone to enjoy "playing very hard on Persona 4"-level of difficulty and time demands.
