Depends if you want to follow the story or just have a shooter "experience".
i definetly want to understand the story.
Then play the first two if you want to know the story.
You can probably get by if you read the halo 1+2 story (plenty of online places but one of the best will be halo.bungie.org)
SEE FIRST POST:
i dont want to play the first game because of the horrible graphics.
Read the books if you don't want to play the first game through, it'll tell you all you need to know.
Personally I've only played 2+3 and I dont feel like there is anything that I couldn't have worked out, except maybe the basic understanding of the forerunners and the purpose of the Halo rings
That's great
you to play through halo 1 and 2???? was wondering this because i really want to play halo 3 however, i cant be bothered to play halo 1 (which i have) and halo 2 because of their godly graphics .
regards
