This was one of the most solid entries into the Halo series since Halo 2 in my opinion. Halo 3, ODST, and Reach just didn't hit the same, perhaps because the story simply wasn't as interesting. At it's core the story here is about the relationship between the Master Chief and Cortana although there is a larger plot going on. I also thought the gameplay was very enjoyable. I should note I only played the single player campaign and cannot judge the multiplayer. I also played it as part of the Master Chief Collection.
