Forty Nine Football was originally designed to play your favorite team through the current season. This quickly progressed into a game that makes replaying any season a lot of fun due to its statistical accuracy, and each game playing like a real football game with many of the coaching decisions needed to be successful. I have played through multiple seasons playing my favorite teams in the CFL and NFL and I'm very happy with the results.
One thing you will find is all of the player and team ratings come from statistics, opposed to subjective ratings. This does make it a challenge with older seasons where statistical data is not as available.
If you own Forty Nine Football, all of the new seasons will still work perfectly with your original game. But, it is being rebranded into two games, Quick Decks Football, and On The Turf Football. Quick Decks is a perfect standalone quick play game where you play through all the plays in a game with realistic stats. On The Turf Football brings in Defensive play calling, and special plays for both Offense and Defense. This is a much more immersive game, but you can still play in just over an hour and a half.
