Checking back in as I continue various testing…..
Looks good so far. I’m gradually adding more FCS teams to the fold to see what impact they have on the overall universe. Here’s a snapshot of Week 13 from the 2022 season:
It’s “Cupcake Saturday” in the ACC! The original saved schedule from the default setup had Florida State playing Miami in Week 12, then playing away at #1 Oregon in Week 13, followed by their annual rivalry game against Florida to close out the season. Of course, in real life there’s no way this would happen. How about a tune-up game against the Kennesaw State Owls instead? Oregon also gets a breather against Eastern Washington before their annual game with Oregon State.
Louisville also gets a breather, whipping up on the Chattanooga Mocs to become bowl eligible.

As for my NC State Wolfpack, I don’t think it’s a good idea (or realistic) to travel to #4 LSU to get slaughtered prior to our annual rivalry game against UNC. So we get the Campbell Fighting Camels to make the short trip up to Raleigh instead.

Lastly, Virginia Tech finds out that perennial FCS powerhouse James Madison means business, as the Hokies have to rally in the fourth quarter to secure the win against the Dukes.

I am seeing some upsets along the way, as happens in real life. Mostly, lower tier Power Five teams and Group of Five. So far, I haven’t seen what I would consider an elite FBS team lose yet to an FCS team.
I’ll continue with the testing and report back on what I see long term, especially as I add more FCS teams. I want to see what the maximum number of them I can add without upsetting the overall stability of this universe.
