My favorite game category is shooters, and Halo 3 is my favorite shooter. I kind've agree that ODST has made the Halo campaign experience challenging again, however, I think that Bungie stopped a little short of completing the package. I love Live Multi player but I now live in a place where DSL is unavailable, so I cannot play online. This has led me to realize that we've come to a point where there are three features that should be industry standards, and all shooters should have them. The features are Co-op, both on and off line, a Halo-like theater mode, and the inclusion of bots for off line Multi player. I really think that the omission of bots for off line play is the one thing that holds Halo 3, and ODST, back from being perfect shooters. It's too bad that Bungie has missed this opportunity twice now. I wonder if the third time will be the charm.
