Dont believe the reviews. it's actually pretty good.
Graphics are alright. not the best i have seen on the DS< but it is still rpetty good. Sound includes "YOUR OUT!", hitting, etc, etc. So, this is way udner appreciated. At elast rent it. It is fun, even with the flaws in this game.
I agree that it could be better, but actually give it a try. You will most likely have fun.
Who knows? maybe MLB 2k8 will be better?
Overall, i reccomend this for at least renting. Especially if you're a baseball fan witha DS.
