Why is it good? Because it takes off from where we left off in good old, Halo 3. The Covenant and the Flood are gone so it leaves you asking the same question "Who is Master Chief's new enemy now ?". Also, I have heard from GameInformer Magazine, that 343 Industries shows a lot of respect for Bungie. I also heard that Frank O'Connor (who has "always" been the director of Halo has joined 343). 343 is also remaking Halo CE which also shows respect for Bungie. Not only is this a good side of Halo 4, but also a good side of 343 who respects Bungie.

Halo 4 is coming out this January. What do I think? It might be good and bad. Why? Because Bungie's gone, and now 343 Industries (I don't know they are) are now taking over Halo Why is Bungie better? Because They've conquered Halo CE through Halo Reach (2001-2011). That's 10 years! Bungie has conquered Halo for a DECAD! AQnd now those 343 weirdos are changing Halo and even Master Chief (look at my icon which is Master Chief from Halo 2 and 3 and compare to the picture of Master Chief from Halo 4! See the difference? I see a BIG difference!
