Good suggestion, JaBurns. I find what has worked for me to prolong the times between ebbing interest in OOTPB is to play out all my games. I used to want to rush ahead to accumulate history and statistics but lately I have realized that the best level of immersion is on the day-to-day level. For me, at least.
If that means finishing a season only once a month or so, then it also means moving ahead and actually accumulating history and statistics because, net, I will be playing the game longer. Too often, 10 or 15-year-old leagues go into the dustbin due to lack of sustained interest. I want one league to persist from one version of OOTPB to the next, as I have seen other players talk about here. I think I am on the right track for that now.
Of course, I will put OOTPB aside again for a while but as I said in the beginning, I will always come back to it. Snap!
