Every time I go to some Halo 4 forum (Especially the Halo 4 Waypoint forums. Ugh.), I see people type up these huge walls of text of how Halo 4 just ruined everything. I have read them and they all have a common cause. Nobody knows how to treat Halo 4 properly. You see, I know people will probably disagree with me when I say this but Halo 4 should be treated as the start of a new game trilogy rather then the fourth Halo game a la Halo: CE. When Halo: CE came out, what did it have? It was a pretty simple package. A great campaign and some fun, slightly configurable multiplayer and that was it. That was IT. No map packs, DLC, etc. None.
But you know what? That was OK because it was the start of something completely new and promising. We didn't give it crap because it was the first game in the series of course. Halo 4 should be treated the same way. 343 may have some veteran Bungie employees with them but they are few and far between in the studio's extensive staff. For the most part, they are definitely new and inexperienced. Heck, I remember that they said in a Sparkast that they spent a big chunk of time and money just proving to themselves and Microsoft that they could make any sort of Halo game.
So, before you post that huge rant that you've spent all of an hour writing, think about it first. 343 isn't out to destroy a beloved franchise of who knows how many fans. But they're inexperienced as far as industry experience goes and as they have said many times before, they have a whole lot to live up to.
