From Halopedia, the Halo wiki
Absolute Halo fan, love the lore and my favourite game is Halo 3.
Halo, Gears of War
Halo, Gears of War, Call of Duty (Not CoD), The Elder Scrolls, etc.
When John is standing in front of Cortana at the end of Halo 3 when Installation 04(II) is firing prematurely. It's a beautiful mix of colours and emotions.
Same thing. Because the Ark took fatal amounts of damage.
Halo 3 is my favourite. Also, the Forerunners are amazing.
