I think most of us play JRPG’s only once, often for the story as well. But are there games for you you already have played a few times and could start that any time?
My most played game at all is probably Final Fantasy X, hadn’t much games as a child and my sisters always deleted my safe state. Even today i play i all 4-5 years. And i guess every Fire Emblem for me because i try to beat different challanges. Iron Man or only certain chars, nothing to hardcore.
I played the first Octopath Traveler for about 80 hours. Quite good game but i wouldn’t play it more often because i always thought it’s level scaling is not perfect, switch between hard and very easy parts. But can’t say something about the second one.
