"It can be tricky to make a good game even better. If you're trying to improve on the best there is, it's much harder. Take NBA 2K7, for example. Easily the best basketball title released this year (and arguably of recent years as well), NBA 2K7 upped the gameplay, the AI and the number of options that players could access. Not really a lot of room for improvement, right? Enter the PS3 version, which provides a new way to fire off free throws and places much more emphasis on the controller and the shot stick."
