Strictly no. They are like FF10 in the sense that you can go places on your own at will for the most part but you are still playing a linear game ultimately.
Yea I’m a sandbox/open world convert too. I still love me some Persona/FF/Xenogears/saga but Fallout ruined me. Skyrim made it hard for me to go back.
I really can’t get into linear games... I’ve tried....
