Halo 1 - GREAT Campaign Mode and set the standard for multiplayer forever.
Halo 2 - My Favorite Campaign, and the multiplayer is very action packed, fast paced, and also needs stategy.
Halo 3 - Not as good of a Campaign if you ask me. But by far the best multiplayer when it comes to graphics, new weapons and tools. Plus has the most custimation when it comes to making a spartan or elite.
its got to be halo 1 because thats the first. the first of every game is always the best. I have played halo 3, but I lost so many times and it is HARD
ima have to say halo 1. the campaign is really fun and... u know what ill have to go with spartan0430. i agree with him almost completly. the multiplayer in halo 2 is kind of fun but gets boring then u go with the glitches
