IGN has a four-page wrapup on how well Halo 2 lived up to its hype, how some expectations were so high they were bound to lead to disappointment, and how the game does, in fact, fall short in some areas. A nicely rounded description-- it almost sounds like it's from a Bungie fan and not an Xbox game reviewer. Thanks Louis Wu.
UPDATE: IGN has added some fan responses to their Epilogue article.
