As much as I love the game, there are some things that could've been done better in my opinion like better graphics... no just kidding. But I do wish there was something new scenario wise in Reach. All of the missions are out of the template of previous halo games(Warthog level, scorpion level etc.). Space Combat is new but for me it didn't feel all that different from banshee levels or the hornett level from halo 3.  

Bah, this is seriously messing up for me... 
 
The friendly AI needs tooling to be as good as the Heroic/Legendary Elites. At the minute, the AI people are pretty damn useless, not even getting in vehicles with you sometimes and many other errors. 
 
I'd have also liked the last mission to be a big amalgam of all the best parts:  
 

For me, I would have liked to have seen/experienced/played more set pieces. It always seemed like a cop-out to try and force the sandbox to create every memorable moment for the player in a story-driven game (Bungie has claimed Halo 3, ODST, and Reach are story-driven). It is a shame that most people will probably forget about the Big Moment "at the end" of Reach and will still remember the nuke going off or things going terribly, terribly wrong for the SAS. As a non-Call of Duty example, how could anyone forget Ravenholm? That whole level was memorable. 
 
Also, I'm getting sick of games claiming to be all about the story and then not delivering on that promise. I don't mind sitting through five minute cutscenes, guys. I'm playing a game billed as story-driven for, you guessed it, the story. Go ahead and put some real effort into your narrative next time around. Jeez.

Kat dies because over-shields don't work in cut-scenes. Also, noble team survives a plane crash, noble 6 survives falling from space, but noble 1 dies in a different plane crash? What. The. Fuck.

Oh yeah, driving AI is terrible. They are much better at shooting.  One thing that would have made it better is that Tron thing that was in ODST.  Night vision can go fuck itself, making this awesome looking game look so shitty.   A way to cycle though armor abilities and a couple more of those abilities would have been cool.    

They should have kept the BR and the alien carbine thing. That is seriously my only complaint about this amazing game.
