Number of Seasons in Madden NFL Franchise Mode: No Fixed Limit - Older Caps, Modern Unlimited

No fixed limit across all Madden games.

• Older Maddens (pre-2010): Often capped at 10–30 seasons.
• Modern Maddens (2010+): Effectively unlimited—play until you quit. Simulated league history eventually catches up to real-world year, but you can continue.

Check the specific game's manual or community wiki for its exact limit (if any).
