Me and a buddy (who grew up with halo while I didn't) randomly decided to play through all of this last night while being sleep deprived as all hell. My guy could literally quote every scene from front to back and I got to fully lunge myself into the lore that is the Halo universe (i.e. me not paying attention during cutscenes and him having to explain to me what the hell is going on). I was always meaning to get around to the Halo campaigns eventually, seeing as I was diamond for Halo Infinite ranked without having played any previous halo game (lol). So it was nice to finally get one done (albeit playing on heroic), and we've already started our journey of trying to play the Halo 2 campaign on legendary. There's a couple of quirks that make this game a little strange at first, seeing as I'm much more of a modern FPS fan, but if you have a buddy who grew up with the game and can explain all the intricacies about it, you'll be having a blast in no time :)
