Don't get the Halo 4 hate, personally. I think it's the best game in the franchise. Speaking strictly about the awesome singleplayer campaign, I enjoyed it a whole lot more than I did the other Halo titles, and I really enjoyed those games. Not all longtime Halo fans are MP players (I get Halo for the SP campaign), and not all longtime Halo fans think Halo 4 was a disaster.
In order of best to worst, I personally label them as follows.
Halo 4
Halo CE
Halo 2
Halo Reach
Halo 3
I haven't played ODST.
Halo 4 was the best game in the series. The presentation was top notch and the weapon balance was much better than in previous campaigns. All the games have been excellent.
I totally second you on weapon balance. I enjoyed the balance of weapons a lot more in this game, and I thought the prometheans were a fantastic addition to the sandbox. I also like the way the campaign levels were setup. I thought the art was the best yet, the levels I feel had more purpose and felt more believable. It enhanced the experience of playing the game because it was easier to imagine myself being in the various locations, and it was easier to see them serving some kind of purpose. I think next gen Halo was partly losing its way. It's not always about massive, wide open spaces, although the fight spaces in Halo 4 are plenty big enough. The art has to help tell a story, too, imo, and I found it pretty difficult at times in Halo 3 and Reach to actually feel like I was actually apart of an environment that served an actual purpose. This wasn't an impression I got all the time, of course, but I certainly had this feeling more than enough times to know I didn't like the impression I was getting at times, and I felt Halo 4 didn't force larger and larger levels down our throats just for the sake of it. I thought the levels made more fictional and artistic sense, and that the encounters felt better as a result, exactly as it was done so well in Halo CE. It didn't feel like some cookie cutter place that you were just dropped into to just start killing enemies that were shooting at you. I thought Halo CE and 2 did a pretty good job of this probably because those games were better designed within their technical limits, some parts of Halo 3 and Reach (mostly Halo 3) just felt like playspaces used for testing, and not really something that was thought out. I know that isn't truly the case, but it's how I felt. It didn't feel interesting enough to me at times. I love some of the battles in Halo 3 and Reach, and all the best ones had a strong aura of planning around them, and were all the better for it. They felt carefully setup and orchestrated, beyond just sending in a new wave. Take firefight, for example, the mode feels like something used purely for playtests, but with nothing really interesting happening around you besides more waves of enemies. That's how I view many parts of Halo 3 and parts of Reach, but Halo 4, to me, just felt right, and the art and design played a huge part in that. It's the 360 Halo title that did the best job, to me, of remembering that Halo is also about taking in your surroundings and often being in awe of what you're looking at, and Halo 4 totally nailed this. It really did.
Halo 4, I feel, is a more tightly (and skillfully) directed and designed game than the others in the franchise, the best since Halo CE, and combined with enjoying the weapons and the fights so much, along with the awesome story and character development for the Chief and Cortana, it made me come away thinking it was the best game in the series. And the icing on the cake? The incredible pacing of the game. I felt as if there was never a dull moment in the game. It kept me hooked the entire time. Even little things like the part where they had Cortana redirect the Chief's armor shields towards boosting the ghost so you could make that fast escape. That was a fantastic idea, and a nice change of pace from what I had been doing up until that point. There's so many things that makes me love Halo 4, especially the kind of hit detection I've been waiting to see forever, the chief being shown off in a way I've always dreamed of seeing, and so skillfully delving further into his humanity and his relationship with Cortana without totally screwing it up. That was a major missed opportunity in Halo 3, and I think we have to be willing to admit that much. That's enough from me, but I love Halo 4. 343i aren't ruining a thing. In fact, I think they breathed some much needed life into the franchise, and despite Reach being Bungie's best Halo game on the 360, Halo was losing its appeal, for me anyway. I have no opinion on MP, since I've never been too intrigued by Halo's MP.
OMG, I forgot how you had to unlock grenades for MP!!!
That amounts to blasphemy, having to unlock one point of the 'Golden Triangle' of Halo gameplay...
It's really telling that I have not played H4 multiplayer to any great degree after playing the multiplayer of every previous title religiously.
I hope they just put the franchise out to pasture for a while, get 343 to come up with their own IP and alternate between it and Halo.
You had to unlock grenades to use them? That doesn't sound like a very good idea at all, but, again, I'm not an mp guy. I'm into halo for the campaigns.
