Has to be Halo 2. The campaign was just so cool at the release date and the online days too.
Altogether I would say that Halo 3, but if I had to decide on one it would be Halo 4, because of its history that I consider the best of the entire saga, as well as the Spartan Ops mode, which gave me the possibility of dreaming of a shooter-looter game by Halo.
My Fav Halo games are Combat Evolved and Halo 2.
Halo CE for campaign and Halo 3 for multiplayer.
My favourite is also Halo 2
Unless counting MCC
My personal rankings:
- Halo 3
- Halo 2
- Halo Reach
- Halo CE
- Halo 4
- Halo 5 Guardians
Halo 3 so much fun playing late nights with friends. Good times
Halo 3 through and through! I don’t even think Infinite will top it for me.
Reach for the great custom games.
I have to say Halo 3.
I was 15 at the time, we just got decent internet, all my mates were still Halo fans; it was all round just a perfect storm of Halo goodness.
That’s not to say I dislike they others, I could sit here for hours talking about what I love about the others, but Halo 3 just came at the right time for maximum enjoyment.
Halo 3. But I’m exited to see how halo infinite tearns out.
Same, Halo 2 defined the shooter on console experience and out of all the maps in Halo, its has my favorites. It’s looking like infinite will be my second favorite though
Halo 3. First Halo I was able to play a lot of when it released so that makes sense 
Probably Halo CE & Halo Reach. Although this changes every few months lol
For campaign/story, my personal favorite is Halo 4 (which turns 9 years old today). I really loved the emotional narrative and characterization throughout its campaign. It felt so human and on par with the books.
Agreed with everything you said. Halo 4’s story is well written and really gives Master Chief and Cortana great character arcs.
I think it has to be Reach for me, it was the first one I played and I thought the story so bittersweet and well written.
Then coming back to it after I’d finished the other games and reading the lore, made me feel the impact of Noble Team’s sacrifice even more.
For me it’s definitely Halo 2!
Storywise, Halo 4 edges out all the other games in terms of writing and overall character arcs. Cortana is just written so well and she actually has a great character arc where she’s the most human character in the entire game.
Favorite campaign for me is probably Halo 3 because there are so many great moments and the sandbox is best in 3. But Halo Reach and Halo 2 are the most operatic with Marty’s score really evoking a sense of tragedy and loss
Halo 4 ending made me cry
