Very frustrating! Hard to control and very inacurate rosters.
The controls espeically hitting are very hard. Its awkward to swing with the wii remote and at the same time move the numchuk joystick to aim your swing. I may get used to this after some time, but even on the easiest settings I only managed two hits as the yankees in a 9 inning game. On the pluss side, the pitching controls work reasonably well, although it seems it would be hard to "hide" the location of your pitches in a two player game.
The other thing there are some weird stats in the game and many players are missing. As my favorite team the Reds, it showed that Jerry Hairston had over 30 homeruns and Jeff Keppinger had 22 last year. These guys combined to hit about 5 in real life!
The graphics are not very good either, although I wasn't expecting much here. All in all this wants me to go back to Wii sports baseball. Why is it so hard for developers to just keep all the "good" in Wii Sports baseball and just add in a few more controls and a mlb license!
