Well, I'm trying to give 343I the benefit of the doubt but I'll admit it's hard after Halo 4, TMCC and Halo 5 which for me overall have been pretty bad. There are things I like about all those games don't get me wrong, but there have been just SO MANY questionable decisions made the last x years that it's hard for me to be REALLY excited for Infinite (though that trailer was good) I think 343I honestly care about Halo, but they need to get away from this "change just for the sake of it" line of thinking. Anyone who's been around since CE or early days especially knows what has worked and what hasn't in Halo. What the majority of the community has liked and hasn't liked, but I think sometimes 343I doesn't. Also, I really wish 343I would have the guts to go away from the mainstream per say...aka don't have things like a sprint animation, don't use the ADS style zooming look, don't put in x thing just because it's big and so on.
One of the best things I've heard them say in recent months is they aren't planning to have battle royal in Infinite. I remember thinking "Finally!!! Maybe they are starting to get it" ....and then with the trailer having more of a CE-3 art style, which is amazing, but the big one for me is the music!! They actually used the Halo themes we all know and love when it's appropriate. About dam time!!! These new songs that they used in parts of Halo 4/5 we're just terrible in the sense they didn't sound haloish at all. We already know the theme when the chief is going to go kick some butt in battle for example. We've heard it for years!!! Then they just go get rid of it....ugh!! Sorry, it boils my blood lol, anyways.... So because of these recent things, I'm still trying to give them the benefit of the doubt that maybe they are starting to get it, but I'm definitely keeping my expectations in check.
