@DethAngel81269I'm not sure how that would work. When we buy a new Madden, I just start a new league and keep the previous league on my site. The issues I see with that are overlapping seasons. If you're on season 2035 in Madden 23 and then buy Madden 24 and start off on season 2023 that's gonna be a problem. At least, I think it would be 🤷♂️
It's definitely something interesting though. And Madden does give us a unique leagueId 🤔
Edit, this is what we do. New Madden game, New League. There's also the issue of when Madden adds/removes rating attributes too. One league could have Passing Accuracy, and then Madden changes Passing Accuracy into Short Passing Accuracy, Deep Passing Accuracy and Medium Passing Accuracy.
