Bought it. Like it, don't love it. If you want perfect ratings on the cases, then that's the replay value. Acting and motion capture is awesome and I'm excited to see where this kind of technology will take games of all genres. I wish there was more to it, or if the game was less linear. Still good though.
Now that i've had a chance to really play the game...... I disagree with most people here. I am definitely enjoying it. Some of the cases really do make you think especially when you have to narrow it down to 2 suspects. The interrogations and motion capture is awesome...you have to really pay attention but the more you do it the better you get at it. It's a different type of challenge than in most games, and i like it. There's enough replay value as far as getting everything done. also, if you totally screwed up a case, it's nice to be able to go back and replay it
