Not cutting down the game at all. The first one was fun to play at LAN parties. The second one was good, but felt more like Halo 1.5 than a true sequal.
What gets on my nerves is the overhyping done by the Halo fanboys.
Look one game will not bring down the PS3. its going to take a long string of games to do that. A gamer will still buy a PS3 if they want to play FFXIII or MGS 4 regardless of when Halo 3 comes out.
Also the Halo series has been as great as most fanboys would like you to believe. Its not original in any way. As a long time FPS I can see where they basically cloned bits and pieces from all the other popular shooters. Basically its in reality part Unreal, part Doom, part Half Life, part Counterstike clones when you get down the core of the gameplay. While that may sound good it doesn't help the gamers getting sick of playing the same tired cloned shooter over and over again under a different name.
