my number one is the soundtracks, make it that the music oozes that halo vibe and that mysterious feeling, like halo 2, man halo 2 had some amazing soundtracks also i still want it where it just defies all the laws of physicals especially for the multiplayer, for example just say your playing a mm game and a box or crate falls and softly clips you and you go flying to across to the other side of the map or youre in a warthog and it just begins to spin out of control for no apparent reason these kinda thing makes halo a hilarious game , and no i dont think the halo reach campaign had the good old classic halo feeling, same with odst and wars, but they are all good games i enjoy them, but for me no chief no classic halo
