If I was reviewing this in 2014 it would be a totally different story. I played this game for the first time in 2018, and even then it was filled with horrible bugs and content that wouldn't be filled in until 3 years later, meaning it took them about 8 years to finally fix this game. However, these are still some of my favourite single player experiences of all time (minus Halo 4). I've played these campaigns over and over and over and over, and will continue to do so forever probably.
