I'm almost certain we'll have that thread, whether it's penned by me or someone else, a few weeks after launch. I know it's not what people want to hear, and I know everyone's buzzing for the game (I am too), but I've got a really bad feeling in my gut about this one. I've seen small changes ruin games: Gears 2, Reach. Halo 4's alterations seem on a different scale to me, and whilst we may not notice it straight away (the core mechanics appear back to normal), the added stuff (armour mods, ordnance, experience system, return of AA's) will, I fear, be on a par with those other games in terms of sending the franchise in the wrong direction.
Again, that there isn't a single innovation or fresh idea in the entire multiplayer suite of a new Halo sets off warning lights in my head. That each new edition can be traced back to Call of Duty sets off nukes in my brain.
