Very nice multi player game and a decent campaign.
Incredibly some Halo super fan, which Im not going to mention, reported me!! and as a consequence I received a warning from the gamespot. That person felt offended because I gave a bad grade to the game and because I said that I was going to sell it back. I swear that I never said anything offencive for that reason I think that the gamespot team don't read what the people write and just send you the warning without investigating. Well thats another topic.
The thing is that I changed my mind. After playing for many hours I realized that it really require some tactics. I learned how to use grenades which is vital if you want to survive the multi player game.
The ability to modify the game in the fork and the many different game modes makes halo super interesting. The graphics are very "happy". Many shooter games are very dark but Halo 3 is fresh, and makes you feel good in the maps.
If I were Bungie I would add a couple of new maps to pull the people back from COD4 and some of the new title around.
In addition, Bungie have a super nice website where you can find a lot of information that you never thought existed from you and from your friends. That's a super nice feature that many other games should follow as an example.
