1. The big one, longer campaign. As much as I loved Halo 4, the campaign needs to be twice as long. It was just too short.
2. Make the game develop it's own story. I read every single book so I got a lot more out of Halo 4 than someone who doesn't read them would, (although reading the books ins't required, I think you would enjoy the campaign more having read the books) but I feel that Halo 5's campaign should be more reliant on it's own story and other forms of media complimenting it. Not the game's story complimenting other forms of media. I think this point is synonymous with No. 1. More story could equal longer length.
P.s. don't rely on Spartan Ops too much for background story. I know a few people who don't have Xbox Live so they can't play. I would hate for them to enjoy Halo 5 less because they didn't play.
2.5. This is a little side one, branching off 2. If Firefiight was playable offline, why can't Spartan Ops? If it is at all possible, Spartan Ops needs to be an offline option too.
3. Please introduce more familiar characters. I love the new ones, but seeing some old faces would be very welcome. Such as Lord Hood and especially the Arbiter. It would be amazing to see him back and fighting with the Chief. Even though he has a more diplomatic/political role, it would be a great thing to see.
3.5. Another little side note. More character development concerning the Didact. We know what he wants, his goals, but he just didn't have that much character.
4. We've known since the beginning that the Spartan II's are/were sociopathic, so I would love to see how Chief deals with this and deals with the loss of Cortana. I know 343i have already stated that this is pretty much guaranteed in Halo 5, but I really want a huge focus on making Chief deal with all of that, plus the weight of humanity on his shoulders. 343i have said Halo 5 will be a dark game and a hug turning point in the series, I want this to have a huge emphasis.
5. No Flood. That's it, plain and simple. The Flood are a massive, important piece of Halo lore, but they were apart of the previous trilogy. This is a new on that needs a new story. And if the Flood DO come back in some away, please, don't make them a new enemy. Just for a few levels or a few cutscenes that add to story. Don't make them a big piece of the new story.
So what do you think? Agree with me? Have anything to add? I wish someone from 343i would see this particular post/thread. It would be great for them to get actual fan feed back.
P.s. The DMR is way too over powered. It needs to be toned down.
