so, im commiting the double posting sin here, but i recon it not as simple as 1,2,3. they where all great, the first one was the goldeneye killer of the genaration, the second one was traling a little but still addded new weapons, modes and continued the story, the 3rd was epic for fans who loved the story (yes, thats me) and it tied up all the lose ends. and come on, you cant tell me they arnt making halo 4!!! who ever finished the last mission on legendery will know what i mean. the trilogry was great, every fps since then has been modeled off halo. halo rocks. nuff said
