Better than reviews say it is...
For example, when you hit a home run, the image of the batter making contact often looks like a pop up. Don't expect to see the kind of detail in 2K10 like you do in the Show. You will not see fans falling out of the stands to reach a ground foul ball, etc. I do like the pace of 2K10. Somehow the games are never boring, and watching part of the game on computer vs. computer mode is actually enjoyable if you have a chore to do and need to stop playing while you take a phone call, but want the game to move along.
The commentators on 2K10 are very good, compared to pathetic on the other game. The 2K10 guys do make an occassional goof, but on the whole they do a great job. In fairness, I confess I am a pick up and play user, and I do not play careers, I just cheat my creditors out of an hour every day by playing games. So, don't count on my advice on the career mode.
