Summary: (Note, I do not have Kinect, so I can't speak on this aspect). Nicktoons MLB is built on the exact same engine as "The Bigs" down to the same taunting motions. Like my critique of "The Bigs," the camera is zoomed in too close for my tastes. The pitching mechanism is actually okay, but the hitting it left strictly up to timing and not location (again, same critique as "The Bigs").
Summary: Before purchasing any video game, I suggest you look up the video game review on Youtube. Here, actual gamers give in depth reviews that are very helpful and accurate. My 13 year old son always does this before asking us to buy him a game.
Summary: First off, this about the Kinect, not the controller mode (which is awful, by the way). The Kinect is pretty good, this is game is fun, however, sometimes, the Kinect will mess up and ''scan'' your move incorrectly. This isn't a problem playing in the beginning, but after a few hours straight of playing, the Kinect gets lazier. When this happens, I recommend stop playing, save, take a break, then start playing again.
