This is a case of GAF bias in action. Halo 4 did a great number of things right that much of the audience here fails to recognize. Unlike every Halo game after Halo:CE, Halo 4 had that sense of wonder and discovery again. They did it by creating an interesting world and with great tech and audio. Even though Halo 4's campaign isn't perfect, I felt like it was as much as, if not more than compelling as some of Bungie's campaigns.
As far as multiple, I have welcomed just about all of the changes that 343 has made. In the end, I am very satisfied with Halo 4 and I really hope 343 keeps pushing it into new territory. Create new things. Dazzle me. Don't be afraid. I for one, am excited that its in the hands of a new developer that can give a new spin.
As far as the story, Halo 4 to me, serves just like Halo: CE did. An introduction. In Halo: CE we didn't learn anything about what was going on. We were just in the middle of it. We learned more about the things we were seeing in Halo 2, 3, and subsequent novels. I fully expect to see more of the Forerunners and have it all come together in a meaningful way. I just hope that 343 doesn't follow the route Bungie took, because once Halo 2 got out the door, the Covenant lost everything that made them an intimidating force.
Halo 4's campaign is easily the weakest in the series, for reasons I could spend pages explaining, but I'll try to keep it to a few sentences. First, the game-play was weaker, largely owing to
SPOILERS BTW:
Weaker AI: enemies ignoring or barely reacting to incoming fire, bugging out and humping rocks and walls, watch any enemy banshee for long enough and it will screw up, and hilariously, every enemy becomes a crackshot simultaneously if you dare to climb into a banshee
Failures in visual design: in every previous Halo, the degree of immediate and concrete information granted by simply looking at an enemy was huge; in Halo 4, weapon and enemy designs are horribly homogenized; needlessly redesign the plasma rifle so it looks super similar to a carbine, make all human weapons into homogenous grey lumps, and good luck figuring out what that Promethean Knight is armed with until he--oh yep I guess his grey/orange blob is an incineration cannon, welp, checkpoint. And so on.
Failures in weapon design: they literally made the most boring possible decisions in 'designing' Forerunner weapons; they claim to have gone through hundreds of designs, and came up with, Glowing Orange Shotgun, Glowing Orange Battle Rifle, Glowing Orange Assault Rifle, Glowing Orange Sniper rifle that does more damage, Glowing Orange Rocket Launcher with a bigger kill radius, and Glowing Orange pistol with a cool secondary fire which is mostly useless in campaign and ruinous to balance in multi-player. Then there's the absurd irony of actually creating mechanically unique weapons to add to the bloated human stockpile like the rail gun and the sticky detonator. Surely they realize at 343 that they could have made those weapons forerunner by simply making them glow orange?
Failures in narrative: they way they must have hacked this thing together is evident from the incredible inconsistencies; gaping holes where information is sorely needed (who are these covenant what is the overall political situation in the galaxy at large) and overbearing info dumps that serve only to confuse the uninitiated and frustrate those who do care to keep up with the universe (meet the librarian). The whole chosen one arc that emerges from that encounter is both stupid, and internally consistent with the campaign design; in previous Halo's, Master Chief is the hero because he saves the day; in Halo 4, Chief saves the day because he's the hero. Why else is it that only he can destroy 4 barely defended flak cannons so that the Infinity can shoot a giant fucking laser beam (which said cannons would have stopped HOW?) and shoot a hole deep into the core of the Didact's ship, only to then be helpless to, you know, continue firing, so as to destroy the vessel with firepower that is clearly sufficient to damage the ship significantly in a single shot. It's because this is the video game level where the video game character wins the video game, not because of any bare-minimum groundwork done to contextualize the necessity of his intervention.
And maybe that would be worth it if this
destined by game design showdown with the Didact didn't resolve itself with a shitty quick time event.
Overall I just can't tell who 343 was trying to please with the story. It's construction is such that it will anger people who are familiar with the lore, and baffle anyone who isn't.
In Closing: I had some fun playing Halo 4, and I don't think it's a terrible game. It is a pretty damned weak successor to Bungie's work, torn between the need to be conservative and safe, and the desire to make it's own mark on the series in terms of narrative in the worst ways possible (didact/librarian retcons, mostly just silly because of how willfully they were done--they had to be really trying to so clearly contradict the mere handful of sentences that existed explaining them--and much worse pretty much everything to do with Halsey, in particular the end of Spartan Ops). In short, they ended up with the worst of both worlds, a game that takes few risks, but 'reads' like enthusiastic and horribly misguided fan-fiction.
I still went on pretty long about this didn't I. Heh.
