Core problem: After finishing the MyPLAYER builder, NBA 2K27 asks you to pick a MyCAREER path. Players get stuck on which starting year to lock in, because that choice decides your rosters, rules, presentation, whether you draft, and which reward track you grind. You cannot drop an existing 99 into another era later. That save is tied to the path you pick.

1The Five Starting Years

EraStartsWhat You Drop Into
Magic vs. Bird1984Rookie MJ hits Chicago. Magic and Bird still running the league.
Jordan1991Bulls first three-peat about to start.
Kobe2003Kobe's Lakers plus the 2003 draft class (LeBron enters).
LeBron2010Superteam era begins (Heatles window).
Steph20163-point revolution and Warriors dynasty window.
Rosters stay locked to real history. Stars stay where they actually were. If you want Kobe as a teammate, he stays on the Lakers for the rest of his real career in that era. You can keep playing seasons after the start year, and the league follows historical movement.

2How to Lock the Year Correctly

Eras skips the normal draft prelude. You pick the era, then pick a team or situation from that start year only. There is no draft process in Eras like there is in the modern MyCAREER path.

3Key Decisions You Will Face

Eras vs Fire and Concrete
First build depends on your priority
Want co-op, Running Mate, or story VC: modern path first. Want legends, period rules, and no 11-chapter cutscene slog: Eras first. You can still go to The City from the modern path.
Which year is best
There is no best overall
1984 for the most history-changing run and rookie MJ. 1991 for the dynasty everyone talks about stopping. 2003 for the deepest real player window. 2010 or 2016 for rules and spacing closer to current 2K.
One save vs many
One save equals one start year
Want 1984 and 2010? Two MyPLAYERs. Each era is a separate save with its own grind. You cannot transfer a 99 build between eras.
VC and season pass
Save story VC for a second character
If you care about the season pass and story VC track, do Fire and Concrete first. Several community threads said to park Eras for a second character if VC is the priority.
