I went full Autist in November 2023 and redid my Madden 2013 rosters to mostly match the NFL's 1979 roster...and then did the Franchise mode adding the real draft picks of note. This blended reality created a Redskin dynasty (powered by a back who didn't actually exist, not Riggins) as they won 7 super bowls in 12 years or so and lost another. The Steelers rode the Steel Curtain to something like 5 more Super Bowls, but only one 1.
The AI of course is flawed, so stuff like the Bears letting Walter Payton go in Free Agency happened even though he was 99 overall, etc as teams didn't properly manage their cap.
Anyway, year 18 in and the game finally glitched and would not let me advance as it said the Cowboys did not have enough backs to play with despite signing a ton to the roster to try and unbreak the game. Sadness.
