One cannot deny the nostalgia that this will bring. Halo: The Master Chief Collection is by far one of the best games I have bought for the Xbox one. For multiple reasons.
**I will NOT be including multiplayer in this because that is not why I bought the game.**
Anyway, the game comes with a mandatory update of 18GB on arrival (Has to be done to clear up patches and bugs so we won't be too harsh on it).
Halo Combat Evolved (CE) was the first to install and to my delight I was able to get straight to it. I never completed all the Halo's on Legendary so I have decided to take it upon myself to do so. And wow is it hard. Waves and waves of elites coming at you in glorious redefined graphics or at the touch of a button you can go back to what it was like back in 2001 which is amazing to see the difference. Sometimes it's actually a bit easier to play on the older graphics as there is less foliage so enemies, weapons and grenades are all that bit easier to spot.
Halo 2 is going to be your worst nightmare if you take on legendary. It looks amazing and will really test you and your drive to pass the game on legendary.
With Halo 3 + 4 it's a small bit different as these are that bit easier to complete on Legendary but will still challenge you they are nothing compared to the difficulty of Halo CE or Halo 2.
In short, if you need the nostalgia hit. Get this game. If you need a good Xbox one game. Get this game. If you are looking for a game that has a great in depth story line. Get this game. Basically what I'm saying is get this game, be the legend that is the Master Chief and pass this game on legendary. You can then die a satisfied human being.
