I haven't played all of them, but I am still obsessed with VIII. I don't think I have played an RPG more than that game. Closest is probably Baldur's Gate 3, but I have a long way to go still. I could never bring myself to play a game more than once, if I finished it at all, and that was the first RPG as a kid, and as an adult, I had the patience to sit and play all the way through and then some.
