You will earn twice as many MVP Points under the Pro difficulty setting, three times as many under the All-Star difficulty setting, and four times as many under the MVP difficulty setting. Also, MVP points are not awarded when games are simulated. The classic players that are unlocked will begin at age 30 and will age and retire like other players.

Select dynasty mode and choose the Yankees. Turn off injuries, trades, rain outs, and budget. Set the difficulty on MVP. Simulate to the last game of each month. On that game, choose to simulate it (not quick sim; choose "Play" then "Sim"). Stop the simulation at the top of the ninth inning and choose to manage the remainder of the game. Do this for every month for the rest of the season. When the season ends, and you see "Advance To Playoffs", save the dynasty. Then, choose "Advance To Playoffs". Each time it will show your points earned.(about 13,000 to 17,000). Do not save after this. Exit dynasty mode, then keep re-entering and choosing "Advance To Playoffs". Each time you do this, you will get that same MVP point amount put into your profile.
