Not gonna lie, I missed the Brute vehicles
With only three variances of Prometheans -- not including the outfitting -- the enemy type was more limiting that I expected and strategies came to become one in the same every mission by later half of the game.
I am glad 343 put out a quality game for their first entry and if Halo 4 is to be compared to Halo CE when comparing the trilogies, then Halo 6 should come packed with content in comparison to Halo 3's offering of vehicles, enemies, and weapons that were included.
I do hope for a Firefight DLC inclusion, but that has nothing to do with the story so I'll leave that to be discussed in general discussion thread.
On the topic of the story: outside of the Spartan program, I could care less what is going on with the humans. I am more interested in the Covenant and they are up to since the end of Halo 3. Also, call me crazy but the muted emotions of the military finding out that their war hero, Master Chief, has returned from a 4-year-absence doesn't present an exciting introduction to the new world of Halo. No one seems to care that the dude that saved everyone's life many times over in the events of Halo 1-3 is back and is about to save their lives again.
In all honesty, I hope 343 takes a few chances with MC and have him become more isolated and disinterested in humanity as it currently stands. Only four years removed, he doesn't fit into their military anymore as he once did in Halo CE -- so 343 should continue his trek to do his own thing instead of saving humanity over and over again in every game. Why not let him break away from the group and set off to visit Covenant worlds, perhaps a short reunion with Arbiter to see the struggle of the collapsing Covenant empire.
Alas, I think 343 will continue down the road of exploring humans a million years ago where they first encountered the Forerunners and Prometheans, along with probably introducing the Precursors in some fashion. It won't be terrible, but the Didact pales in comparison to Gravemind and even the nefarious Prophets. The Didact reminded me a lot of the weak Romulan, Nero, from the new Star Trek. I hope he was a one-off villain and won't be brought back in current form and is only referenced or shown through flashbacks.
