For me, personally, this is my favorite Halo. A lot of my friends also think this is the best game in the series. There are so many great Halo games that there are so many different answers you get when asked what your favorite Halo game is...
Halo CE, Halo 2, Halo 3, ODST, Reach...
I'm fine with anybody who disagrees with me on which Halo game is the best (unless you think Halo 4 or 5 is the best then I will rip you apart) because all of the original halo games are all amazing, and almost all equal to each other in terms of quality despite being different. But just in my personal opinion, through all of my experiences playing this game, I will say that it is my personal favorite. Great game.
