Personally, Im excited for this game
I personally enjoyed Halo 4's story. Music? Not as much as Bungie's games.
But all-in-all, I feel like 343 is handling the series well. Halo 5's multiplayer is very eSports based as well, which is a good thing for me, being very competitive in multiplayer.
We'll just have to see what happens when the game comes out.
