The good Nuggets Retro Jersey
As much as I can kind of dig the blue and rainbow jerseys on a kitsch level, I'd love for the Nuggets to have the choice of this jersey too. It's my favourite.
Draft Class Edits
Since the PC version is non-existent, I'd like to see Elite do what 2k allows you to do with draft classes.
Retired Jerseys
Not just the ability to retire them, but the game to pick up the fact that 23 for the Bulls and 2 for the Nuggets are retired numbers that cannot be used.
Control the players destinies
I'd like the ability to choose who progresses in their careers as opposed to being assigned it. For example, if Shaun Livingston is actually living up to his potential, I'd like to see the skill ratings to act accordingly.
More complex contract clauses etc
It seems a bit too easy sometimes to sign/deal players in NBA Live games. With Bird rights, trade kickers and team/player options, it'd give the user more to think about when they're wheeling and dealing so to speak.
-----------------------------------------------
I'm sure there's more but I can't think of anything else at this point.
Haven't really had the problem with retired jerseys being used, but might come across it later on in my dynasty.
