Halo 2 is both a good sequel and a disappoitment. The single player campaign is good, but not nearly as dramatic or climatic as the original Halo. The new weapons are mostly well balanced, except for the Energy Sword. I find that it is way to powerful for muliplayer. Also the multiplayer matchmaking is a good concept, but should have been made optional not mandatory. I often find myself waiting 3 to 5 minutes just to get into a game. Also, there are times I would like to have rematches with people I just played, but in order to do that you have to befriend them and set up a nonranking custom game. I greatly enjoy multiplayer besides those problems but am somewhat let down with the short single player campaign.
