Thanks to Noah I bought an old copy of the Master Chief collection ((I tend to never buy games when they initially come out – I wait till they are older and cheaper)), which includes the remastered versions of Halo: Combat Evolved and Halo 2. The remastered versions of the games are seriously incredible. I loved being able to swap between the original and remastered versions during the cut scenes. They are of such high quality that every now and then I forgot that they were computer animations.
Halo: CE, 2, and 3 are such good games. Halo 4 not so much and I can’t speak for 5 yet since I haven’t played it … yet.
