Summary: I tried playing both 2k12 and 2k11 on two different Nintendo DS systems and, at the last out of the game, after playing four or five games of a season, the system would freeze. I tried playing three or four more games and it would freeze at the last out of each and every game.
Summary: Both of my sons (age 6 and 9) love this game! It is their favorite DSi game and they want all of the other Major League Baseball 2K games too. They love being able to be the actual players from their favorite teams.
