Well, I own a 360 of course, so, of course I own Halo3. Well im not a fanboy or anything, but I do have a lot of friends who own an Xbox with Xbl and they often play Halo3 together. Here's the problem. Only 4 maps work, despite me downloading all of them, including the legendary pack twice. Yes, paying twice as well. Well, the Xbox360 that I own also flips out when i play the few maps i play the usual hum of the xbox is replaced by a somewhat sounding "turning on" sound over and over, and when I try to go back to the dashboard (through using the guide button and pressing y) it shows a black screen and never gets to the dashboard. When I try to restart my Xbox, I turn the power off, and there is no light on the ring, but it is still running. I have to press it again, it will turn back on the ring, and then I finally press it a third time, turining it off. This has never happened to me for anygame, and still is, I can play every other game without any problem whatsoever. What I've tried so far is i have deleted some memory with halo3 and other stuff like my music. Well, I had 365 items for Halo3. My brother owns 2 profiels and I own one, so we do have alot of memory on Halo3. I degraded the memory content to 140 items, and now, I can play matchmaking. Before it didn't let me, so i have gone somewhere with this problem. Anyways, I need help with this as you can see. Any tips or ideas would help me ALOT. Thanks, everyone who helps. :D

Really? PS3? Yeah, those are all good games, but that's it. That's the only thing the PS3 has to offer in my mind, and if you check the back of most of the games ( The box it comes in ) all PS3 games run in 720p or i or somthing. Anyways, most of the other decent games the PS3 has are also on Xbox360.

Doom4, Forza Motorsport 3, BioShock 2, Dead Rising 2, Odst.
