Aye man, how about some more Covenant! and some grunts and elites and shit.. yeah. I'd be surprised if they tried to be innovative with this Halo release, but remember folks this is Halo. They won't stray too far from what Halo is already, so don't expect anything mind blowing. Still, Halo can be fun if you're willing to have fun with it. I''m a fan I guess, don't really care much about the franchise anymore, but whateves.
No, this game is different in tone. That's okay with me. I'd like it to be different than Mass Effect 2. Plus you've been with these characters for years now. No need for more character development. Besides, a giant war is going on, there is no time to deal with personal stuff like in Mass Effect 2.
