Me and my 2 boys purchased 3 copies the Monday night it came out, I found me a used xbox so each of us could play.  It is an awesome fun game.  My boys, who were way more into it than I can even digest, really have enjoyed and gave it a thumbs up.  It is a blast to play.

 I enjoyed this as well.  I beat it but am playing it on Legendary now.  Not sure if they put in a different ending but I like to try it on the hardest at some point.  Enjoying the Multiplayer so far too.  Nice job by 343.  

I'm not going to spoil anything but the ending left me a bit fuzzy as to whats next.  

 Only played 2 chapters of the campaign but the online is pretty sweet.

I'm on the last level of a solo Legendary run..  I think I'd enjoy it a little more if I was playing on Heroic as sometimes dying over and over in a few spots can get old.  I do agree Legendary on Reach had a few more tough spots.  I miss the Covenant speaking English a bit and some of the quips they would say about MC being a demon and all.  I guess it makes sense that they would speak in their own language.  But I think the sound effects 343 have done has been awesome.

I've only played a single match online so far and it was when I first loaded the game and didn't know the controls.
