Custom Season Mode
The new custom league offered in franchise mode is really cool. However, this still limits to you only controlling a single team. In season mode though, you can control the entire league. I think you should be able to also have a completely custom league in season mode. Meaning, you can still have the option to do a single season of any of the North American or European leagues, but there is also an option for a custom league where you can decide how many teams, the length of the season, the playoffs, basically everything you can do in custom league in franchise mode.
The reason I want this is because I try to create Custom League's, or even put NCAA into the game. The closest I can get to an NCAA season in NHL 24 is to do a season mode with the NHL option and import my 32 custom teams. But this of course isn't too accurate because it'll play 82 games and restrict the postseason too. How cool would it be if I could make a custom league and set it up to be just like the NCAA? This would be possible with a custom league in season mode. You can do the custom league in franchise mode, but you can only control one team, which sucks. I guess if they just make it so you can control multiple teams in franchise mode, this wouldn't matter, but seeing how this hasn't ever been an option in the EA NHL history, feel like it would be more likely they can just give us the option to make a custom league in season mode.
