As for the new Halo 3 for XBox 360, it totally rocks! The storyline, graphics and gameplay are all sweet! Of course, on-line Multiplayer is the real money maker.
Another nice feature is Forge Mode where you get to edit the existing levels as you please. Setting it up the way you want is quite nice in my book and makes many different possibilities of how you want it.
I'm so going to love this thing! I highly recommend it for ANY Halo fan. ^_^
