MLB Power Pros is the deepest baseball game to date and can be customized to suit almost any type of player.
There are also modes where u can create your own league and play up to 10 seasons using Season mode where you can manage a teams players salaries, income from games, and all the day to day operations of a GM. If you don't want to get that deep you can customize it to your taste and tell the computer to manage and even simulate games according to set preferences. In the Training mode you can have players practice together in small groups to build friendships and pass on certain skills if their friendship level is high enough. The Practice mode needs a little TLC in the next edition of the game but is still fun nonetheless.
It also has the standard exibition and HR derby modes where u just dive right into the game and a deep practice mode where u can take batting or fielding practice to develop your skills. Believe me, depending upon what level of automation you use you will need to practice just like the MLB players do in order to be competitive.
The Wii controls are basicly only used in exihibition and HR derby modes and at first I thought this took away from the gameplay. However, it turns out that the game is better that it doesn't depend on the Wii controllers heavily. It is such an indepth game that it would give it an arcade type feel if the Wii mote was used in the season modes. You still need to be accurate with the nunchuck and the remote in order to hit or you can use a gamecube or classic contoller to make it bit easier.
The Success mode is fun and with its RPG type syle makes the create a player mode fun and enjoyable. You have to constantly make decisions which affect how your player is created and what skills they will have if they are offered a contract at the end of the mode. Like in life you aren't always offered a contract at the end of your college career if you don't perform well enough and/or the scouts don't like you.
The only major thing I don't like about the game is the announcer's tone at times is way too excited, that he constantly repeats himself, and his speech is not fluid. He does come up with some pretty kewl little tidbits about players like then they are about to hit a milestone in their career he will say something like "David Ortiz needs only 8 more home runs to hit 250 for his career" which I think is pretty cool.
Finally, as far as replayability it is extremely high with all the different modes and ways to play the modes. I plan on spending a lot of time developing and creating new players and teams and then taking them to glory! Definitely pick this game up for fun for the whole family and don't let the 'kiddie' look fool you! MLB Pros is the real deal!
