when you finish "the nba's greatest" mode, does that unlock those players for the "creating a legend" mode, similar to how it worked in 2k11 with MJ?
i'd love to rebuild Wilt from his rookie year, for example. growing his attributes from his rookie season on up.
or Kareem for that matter... start him out as Lou Alcindor on the Bucks... see his appearance change over time (and his name, that'd be a nice touch)... get him traded to the Lakers...
