I've noticed in the road map that "create league" is a possibility in the future. I have been thinking that it would be nifty to be able to create a league in which you are the only human player and all the other teams are AI.
If this were to come to fruition I would imagine it being essentially the same as all the other leagues, except the individual who started the league acts as the commissioner of the entire league as well as an owner of one team. In a way, it would be a sort of MFN sandbox mode.
Some of the features I could foresee:
-Allowing trade among all other teams even though they would be AI.
-Setting a difficulty level among various aspects such as willingness of other owners to trade with you, abilities of other coaches to game plan, or just overall difficulty in general.
-Setting how much talent is in a draft.
-Being able to edit other team information like names, city locations, maybe even being able to edit the intelligence or skill level of the owners of other teams.
-A "create a player" feature where you could essentially create your own player and their skill sets, weight, height, name, and position, and they would drop into the draft or free agency.
There are probably a lot of other cool features that could be thought of but you get the gist.
I know this would take a lot and most likely would never happen; however, I do believe it would be a blast to be able to play "king" and run a league.
