I wonder if anyone was as disappointed as I was with Halo 3:ODST. After playing Halo 2 back in the day, I remember saying to myself that no Halo game would ever suck as badly as that one. I was wrong. What was Bungie thinking?? With the exception of the two Vidmaster challenges (Endure and DeJaVu) there is absolutely no challenge at all to this game. It is very sort, and the legendary difficulty is comprable to that of normal on Halo 1 and Heroic on Halo 3. The Firefights are Bungie's attemp to give the game more playablity. What is my opinion?? Don't waste your money on Halo 3: ODST, save it for Modern Warfare 2. Call of Duty has never disappointed.
