Sounds great, BTW there was a reddit AMA from a therapist who researches the intersection of video games & mental health[1] the comments section includes several people who share similar experience as us.
I'm planning to try out JC3 for it's interesting game mechanics as you pointed out. One thing I noticed after getting hooked to PUBG was, story based gaming doesn't interest me anymore; I used to be an avid gamer before my entrepreneurial commitments, I would definitely finish the games.
Not sure if it is 'endless' nature of PUBG or similar games, which doesn't give the content of having finished a game; makes one hooked to them. I had got NieR:Automata for it's philosophical adventure, but I didn't get back to it since I touched PUBG.
P.S I wish good health for you in the coming years.

So glad I found someone else who also got help from games for their anxiety and panic attacks. I've also undergone some crappy health-related stuff this year and the only thing which I believe pulled me out of it and fixed my crippling anxiety while I recovered was Just Cause 3. I think it was the wingsuit flying coupled with the open-world exploration. It was basically the only activity which could bring my heart rate down to the 60s (It's very counter-intuitive, even for me, how a fast-paced game managed to calm me down) . Not even reading had this effect on me. My friends don't play games and I'm not social at all (twitch, xbox, etc..) so I'm very glad I see someone else in a similar situation.
