Halo 4:
- Prologue cutscene.
- The whole section on the Dawn where you have to launch the missile, then requiem opens.
- EVERYTHING about the second mission, especially when you emerge out of the crash site and see the massive floating towers in the distance with the music in the background. And when you're inside the cathedral with the ethereal choir playing as you explore.
- Awakening the Didact.
- Infinity's crash.
- Meeting the Librarian.
- Cortana losing it and screaming at Del Rio, who then screams at John who rejects his orders.
- The following scene with John, Cortana and Lasky. Cortana contemplating that she knows why the sun isn't real, but will never know if it feels real.
- Flying the Pelican.
- Halo theme playing when Installation 03 is revealed.
- Tillson and the other scientists getting composed.

- The ending.
- Epilogue scene.
Also the part in Reach where you Storm the Beach, see New Alexandria get glassed as you fly your Falcon around the Crumbling city, the cut scene in the oni facility where trooper and covenant corpses are littered around a devastated facility after a viscous battle and that cut scene with the sabre launch were amazing.
And the Part in ODST where you meet the engineer and the final warthog/tank run.
