After seven years, every single cell in your body would have been replaced. Does that mean that you are no longer the same person, are you somehow someone completely different? No. You are still you, a modified you, who has been changed. Halo 5 is still a Halo game, it keeps core aspects, but other parts of the game have changed. Change isn't something we can escape, would everyone like a H2 clone, because that's the best Halo game? No, no they wouldn't. Halo would just die. Gamers want originality and excitement, and hating a game because it wasn't made by Bungie, or wasn't a copy and paste job is just stupid. Halo 5 has a great multiplayer, brand new mechanics, awesome gunfights and an okay story. It is an awesome game, whether you like it or not.
