It's entertaining, yes (albeit, I haven't finished the game just yet). Fucking different, that's for sure. 343i switched to using Havok Animation and AI for Halo4 and Wwise for sound, where Bungie rolled with their own developed tech. I don't know if it's the TV I'm playing on (using HDMI, so...) or what, but the music barely feels like it's there (did any of the previous Halo games provide a volume setting for music/dialogue?), and the same goes for the some of the character dialogue.

I'll say this much...if 343i itself were to be the ones to work on Halo Wars 2, I would be very hesitant to get excited. I want a sequel to fucking Halo Wars, not 200+ people 343i does Halo Wars.

I'd really like to see a competent gamer who has never played previous Halo games play Halo4 for a few weeks, then go back and play all the Bungie games and see what they turn around and say.

Oh and 10 of the 13 MP maps in Halo4 were developed by Certain Affinity if the file name prefixes are of any meaning.
