Honestly, do you really want a game to stay the same all the time? Won't it grow stale after a while? If Halo 4 was just like Halo 3 with just better graphics and new weapons/maps, it would become boring pretty quickly in my opinion. I prefer changes that provide a refreshing and new experience. I understand that you want Halo 4 to feel like the Halo games you love, but times change and so do games. Cherish the old memories, but move on and create new memories as well. Don't just sit there and think back about what used to be great, that way you won't be able to enjoy anything new.
