Great for baseball people, meh if you are not.
The major draw would be the season mode. The script and voice acting leave parts to be desired, but the look and game play is good. My dad and brother go really into the tweaking and customizing of their teams. There is even a training mode where you can boost your players abilities after some time in the batting cages or on the pitchers mound. You maybe turned off by the oversized heads and cutesy appeal of the game, but the style works well with the Wii since realistic people do not seem to turn out well on the system.
For me, this game was not ideal. I did get the basics of playing a baseball game, but all the information about which pitcher I need when I am one run up vs a tied game was lost on me. If you like baseball and the intricacies, you'll be happy with the game.
