Not sure how successful that would be. I don't think most people would want an Atreus only game. The character just isn't that interesting without Kratos.
Also personally I'm not a big fan of the direction Ragnarok went. Felt like a rushed Marvel movie compared to the more serious tone of 2018
Felt it in Tokyo. Slight shaking for about half a minute. I can't imagine what it's like in Ishikawa now
