I guess my thing is, as much as I love them, the classic main-line Halo formula as a "game" is getting stale
It really seems to me, that with Bungie leaving Halo, they will end up making the best "Halo" they ever could, because they got to drop all preconceived notions.
Destiny is still sci-fi, still a FPS, still competitive and cooperative modes, still huge story, but they were able to create a game for the future.
I love the Halo campaigns, I truly do, but they need a refresher to stay exciting for another decade, 8 missions and you're done simply will not be good enough at a certain point.
As for Multiplayer, I truly believe that Guns-Grenade-Melee can work as it always has,
But.. the world around Halo has changed significantly, and (Armor Abilities) were a needed addition
, just to keep up with the competition in terms of feature-sets if nothing else.
Halo with more than 4 players needs to remember that it is at its best during Objective play, I have a play group of 6 players, and its gotten really boring for the past 9 months to only play BTB Slayer, or Dominion.
Smaller team sizes should be focused on competitive play with tight restrictions, and Larger team sizes should be focused on cooperative play with player choice being prevalent.
Are Spartan Ops and Firefight truly as far as it goes for Co-op experiences?
I hope not.
I love Halo, the games, the books, the crazy fans, hell, one of my biggest passions has been forging old maps into the new games, but when I think about being nearly 30 or whatever and waiting for (Halo 6) I really don't want it to be a prettier Halo 3, it needs more.
