Even though I’ve never played the first game (I know, I’m planning on getting Anniversary), I just wanna hear from the community which of the versions would you prefer?
Halo CE
Halo CE Anniversary
They’re both the same with few exceptions. 
Anniversary is not out yet so nobody can have a real opinion on which IS the better game. But honestly, Anniversary is supposed to play true to the original, and simply enhance it.
So in the end I think Anniversary is the way to go. Especially since Anniversary comes packaged with the original game (at the press of a button).
They’re the same game. For me, it will just be a matter of how I feel at the time. DO I want to play old graphics or new? It’ll vary.
CE, CEA won’t have the original multiplayer
> CE, CEA won’t have the original multiplayer
I’d get CEA, I don’t have know many people who would come to my house to have a lan party to play CE. While you can use XBox Live to play the remade maps (though they aren’t the original one)
