I currently have a Wii, PlayStation 3, Nintendo DS, and PSP. Halo 3 sounds amazing and I'm thinking of getting a Xbox 360 to play it, and also Xbox Live and Gears of War. So should I get one or not?

You have everything else, why not? I think 360 has best library of games anyway so far, and some older ones are cheap.

yeah, why not... you should also get Guitar Hero 3 (comes out in fall) for the 360!

If you want it, most certainly. No other system has the current line-up of the 360. Grab an Elite 360, if possible. It has HDMI, a hard drive 6X bigger than the Premium, and it's only 80 bucks more. And, there's bound to be another Gears of War, as well as several other titles you may find an interest in.

I'm also thinking of getting either the 20GB or the Elite can't Deside on none or one of the other. And REMEMBER I am only 12 years old and my birthday was 2 weeks ago.

Damn Joey! Your 12 and you have all of this stuff? Nice parents. I would get the Elite. Heck if it doesn't matter to your folks might as well. It's not that much more and has some nice upgrades. Plus it looks sweet. Oh and if they are feeling really generous I'll take one also... No. Maybe next time then. Have fun!

I save up ALOT, and plus whats the diffrence between 360 and PS3?

for just a Halo3 - NO, for other good games YES. Halo3 is just overhyped. On ps3 this fall you will have nice MP games like Warhawk and Haze. Well, if you have vista on your pc, then just try to download or rent Halo2 on your pc and see do you like it or not. =)

I'm Mac not PC. The worst computer is PC.
