I would love love love for this to exist, and would be willing to work on it long term, but it's no trivial task and I have no clue where to even begin.
While we're in fantasy land though:
-unlimited team number, easy to add. Probably you choose team, then roster year.
-jersey selection before games
-optional enhancements to 94 gameplay; pass speed, turning tightness, lane filling in O-zone for wingers to one-time from slot...etc
-HD graphics to see more ice surface (full side to side view)
-online play with stat tracking, league support
