When it comes to Halo, Halo: CE is on the top of my list. Halo 4 would be 2nd best with regards to a more all around game. Campaign and Multiplayer were more polished then Reach and Halo 3 making it a much overall better game then Reach. Campaign wise I felt was good but not as good as Halo 3 (top of my list for campaigns). Definitely a must have and a must play.
