I recall the game recording feature feeling pretty cutting edge at the time, as you could pause it and rotate/fly round the scene, it felt really fluid and responsive. I guess now it would be common place but back then it definitely seemed a little magical.

Are you thinking of Theater mode that first appeared in Halo 3? Unfortunately it was slimmed down in later Halo games and it is rarely seen in other games at all, especially not console games.

This was common in PC games at the time, but not on console games. Essentially you're just dumping game state memory somewhere and then replaying it. Half-life games had it.
