Halo 2 and 3 were the games I was most excited for going into this collection, and I'm glad I got to play them. Every single little thing from CE and 2 that I had an issue with is fixed here, I genuinely have zero complaints here. The story is just as great as it was in 2, the level design is the very best I've seen in the series so far, the OST is amazing as per usual, the characters are all great (I love the Arbiter) and the set pieces are genuinely intense and get you hyped up. From fighting the Scarabs during The Storm, breaching The Citadel in The Covenant, or the final Warthog Run in Halo, each level has many action packed moments that make this game intense and really make it feel like the climax to the war, a perfect follow up to the cliffhanger of Halo 2. Overall, I would say this is a very impressive campaign and somehow managed to exceed the high expectations I had for it.
