Definately a game worth buying , and at least rent if you have no interest in flying games - it will change your mind
My favorite if needing to be chose would be the soundscore, just magnificent. They actually did go to the San Francisco Zoo and did many recordings to get it all perfect, job accomplished. Take a min and appreciate it. Concert Hall really good idea as welll.
The graphics are something I do not need to address really - like duh, they ROCK. Can you say WATER , i swear it has its own AI
Enjoy the game and like the days of Golden eye get ready for some crazy replay value.
