(Note: This is part of me going through all of the campaigns in the Master Chief Collection, my thoughts are only gonna be about the campaigns and nothing related to the multiplayer/online play)

While the campaign started to get bullshit around Mission 8 or so, I still had a lot of fun with it. The story was incredibly interesting (Though I wasn't sure what was happening half the time until the end), the combat and weapons felt incredibly varied and fun to use, the pacing was very tight, and the whole thing felt super immersive. Outside of the sudden difficulty spike, being unable to make properly save states like a lot of other FPS games I'm used to, and not being able to keep weapons in between missions/when you resume a file early in a mission, I can see why people bought an Xbox just for Halo. It still feels very fun and refreshing to play even after over 20 years.
