I bought this as a gift for my kids.The disc wouldn't play in the XBOX. It doesn't appear to be dirty or scratched, it just doesn't play.No other XBOX title we have (more than 20) has this problem.Even though Konami's warranty states that they will replace any defective item, they refused to do so in this case because it was bought online. There is no language in the warranty distinguishing between buying online or from a traditional retailer.PS: Even though it was beyond Amazon.com's 30 day return period, when I explained the situation to Amazon.com customer support they immediately shipped a replacement. So buy from Amazon.com, just don't buy Konami products.
