Got around to doing this today. I ran the wizard, only thing I unchecked was “import historical records” (or at least that is what a I thought I was doing - starting with no record book like baseball was just invented). I’m running the default first which is development engine with no recalc. I have a discrepancy from what was reported however - retire players / miss seasons was OFF by default in my game (and I’m running it that way).
