Ok, so I just finally bought Halo 3 recently and sat down and played an hour or so on my 32" Sony Wega. (standard def)  I put it away because I'm still waiting on my 42" LG LCD to play on and I don't want to ruin it, lol.

Halo has taken a lot of heat since it was launched for a number of things but I can tell you this:  after having played just an hour, it is leaps and bounds above Halo 1 and 2 graphically.  Now, why is this thread in gaming instead of microsoft?  Well, there is a little feature called theater mode that I think is quite cool.  I've not seen it in any other games and it's quite revolutionary.  If any other game has done this, let me know what it is... I know replay and screen capture have been done before, but I don't think anything even remotely close to this level of control has been included.

So, basically, after having played part of a level, I went to theater mode and discovered you can watch the replay.  Replay... No big deal, right?  WRONG!.  You can play back the replay from the perspective of others in your party, close behind the Master Chief, far back, or even in "free camera mode".  The free camera mode is freaking awesome as you can pan around, zoom in and out and just take in all of what transpired during a battle.  It really is quite cool to go back and watch a battle while zooming around and checking it out from the bird's eye view or from the enemy's side.  Everything remains rich in detail and you can basically "camera wander" anywhere in the level that your people have been or the aliens have been.  I can't say enough about how cool this little feature really is.  All of this can be done while motion is happening so you watch live or you can pause it and examine everything in place.

I haven't even begun to explore other areas of the game yet but this feature alone is worth the price of admission...

There is that replay cam on Pro Evo, but its not the same
Also, the Ace Combat games have a replay feature at the end of each level, but it still leaves alot to be desired. However, it does make you look great

Getting out of levels with the cam in the theater is kinda fun, especially if you like to break games and see how the levels are set up.

In Halo 2 you didn't need a camera to get out of the level and discover the rich amount of glitches to behold :D

theater mode is AWSOME

theatre mode was a good addition to the game

These walls are there to stop you going to far ahead in the level. why? As the Legendary Edition DvD's tells you, there are points where the enemies will just appear out of thin air when Masterchief goes past a certain invisible checkpoint. The walls stop you seeing this when you hit play 2 miles down a level.

Theatre mode is awesome. Its a nice way to add insult to injury when you get a particularly nice kill on a buddy.
Clip it. Save it. Play it over and over :)

Yes its been done before but I agree the ease of use and level of control are great.

Im hooked on this game. Bioshock, which I havent finished, is collecting dust now. I'll dust it off soon though.

Theater mode is pretty cool when you get a lucky stick using the grav lifts or something (I have two), it's so awesome watching them again and again.
