While Halo 3 is my favorite game, I still am very disappointed with the campaign. Before the games release, I expected the game to be based on the earth and so when the game finally came out, I was very disappointed. I really did not like the campaign levels. To me they did not really look like Halo. Halo 3: ODST, however, brings back the look from halo 2 and is based on Earth. This has me really excited.
