And the answer depends on how much you care about the story and what kind of play you want. I never played Halo 1, actually -- I started with 2. It's probably not worth going that far back. I guess ... 2 has a longer campaign than 3, so if you're into the solo campaign, 2 is probably a better place to start. If you're really into playing online, you should probably get 3, because so many people online will be playing those maps. Hope that helps!
Help please. I bought an Xbox Elite to play Halo. Should I start with 1, 2 or 3?
