I can see this is going to be hit with a wall of flame, partly due to the topic but also due to my extremely low post count, but please, bare with me. I’ve heard a lot of discussion on these forums and elsewhere questioning decisions made for Halo 4, which 343 say will differentiate this game from the original trilogy, and also continue Halo’s evolution. In my opinion, so far the changes announced seem ok to me, I have an open mind and I don’t think 343 would intentionally change Halo’s style drastically.
Here’s where people will get angry…
Call of Duty: Black Ops 2’s trailer was released yesterday, it showed something I wasn’t really prepared for. But DAMN does it look cool. People have been saying since MW2 CoD needs to do something big to change things up. Well here it is, BO2 is so far from any CoD I’ve ever seen it could be passed off as a Tom Clancy game. All I hear is ‘LoLZ, TRAYERCH CoP3d H4L0, Not GoN BY’. 
Why is there constant flame wars over what franchise, console or company is better? If you don’t like CoD no one is forcing you to buy it. Don’t like the gameplay, graphics, story etc. that’s cool, but don’t throw hate at me because I love both Halo and CoD (apart from Mw3, that was terrible).
What’s funny is that people don’t seem to want Halo to change, but complain when CoD doesn’t, and when it finally does everyone chucks a tantrum.
Just my two cents.
