Halo 3 stands as the most beautiful game in the Halo series, and on the Xbox platform as a whole. So many years later, the use of color and art in this game makes it look incredible, not to mention its phenomenal soundtrack composed by Martin O' Donnell, that's a combination of old and new, reincorporating tracks from previous Halo games to reinforce (what was supposed to be) the end of the Master Cheif's journey.
The variety of weapons, the scenery, and the character that fills this game is something incredible, making for an experience that never overstays its welcome, and stands as a monument of beauty, unity, and finale within video games as a whole.
