Overall, MLB2k6 isn't too shabby. Although it's not as impressive as EA's long living legacy, but it gets it done.
However, there are some bright sides to the game. The hitting system is very nice compared to previous baseball games. In a lot of baseball series you simply click a button and the ball goes flying through the air. MLB2k6 is a little bit different . . . you have to learn how to step correctly before you begin to crush the ball. Even though, once you figure it out, you're able to crush the ball just like every other game.
Overall, the game isn't too impressive. But, if you're a baseball fan, then it's worth it. But, for the most part, I suggest waiting until the price drops.
