If you haven't played any of the previous mods, like 2K17, Double Z, or 2K20, make sure you play this one. Such great love and care is given to this series.

Only 148 hours compared to the previous 2K20's 213 hours, what a downgrade!

 :laugh:  Indeed.  I got lazy!

TBH, if you just wanted to do a roster update for Jam, you could now use 2K21 as a real solid base (2K20 too, actually) and probably get portraits, attributes, and text/roster in somewhere between 50-75 hours annually.  I just got caught up in the opportunity to learn more about the game, do some clean-ups, and knock out some enhancements from my Hack Ideas thread post from a few years back.

The delayed season was also a big motivator in me picking up the hack again, as it gave me plenty of time to fiddle with portraits and ask more questions about ASM concepts.

Enjoy the game!  :beer:
