ODST was amazing. Beautiful graphics and a beautiful city.
The story was outstanding, and seeing that assault cruiser come up close and just glass the planet was devestating.
Sadies story was great. I was really sad near the end. That's the most I've ever wanted to do something in a video game. During my first playthrough, my thoughts were: "FIND THE NEXT AUDIOLOG NAO!"
If they made an ODST 2, and made it basically the same, I would buy it. I'm just afraid that if they made ODST 2, they would change it too much.
Also, Music? Fantastic. Really set the mood of the game.
