Halo is a lot like any otehr trilogy. The second one is SUPPOSED to lag, it just sets up the third one (think LOTR) The first one establishes the basic plot. This applys to almost every trilogy made (True for Star Wars (both) as well, except Empire Strikes Back was the best by far) So, the third halo will absoluely pwn. BTW I have halo 2, and its story is nothing like the first. Second, the Arbiter and the Chief will probably team up in the third one.. My only complaint about halo is that u have to read the books to get the whole story
