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 have a rotation of Final Fantasy 4-8 and Chrono Trigger that I play on my phone. Sometimes I go a few years without playing, but overall I've lost count of how many times I've played in the 10 years I've had a smartphone.
