I just finished the single player campaign and I've got some gripes.  I played through the whole game on heroic and I was fine with this difficulty until about the seventh level. That's when the game reverted to the old halo format of kill one guy, run as far away as possible to get a checkpoint and then run back.  Rinse. Repeat. It becomes a battle of attrition with the biggest casualty being the fun.  I think the reason I had such a boring, grind-y time towards the end is the unavoidable fact that the AI is too intelligent.  Almost at all times I felt like I was outgunned and out-skilled. The enemies went as far as tagging me with a plasma grenade seconds after I died (almost every time) as if they were programmed with taunt functionality.  Don't even get me started on how much of a chore it was to kill the super elites that were white or the zealot class elites that are seemingly the only beings sentient enough to wield two weapons in this iteration.  Anyone that is tired of a two hunter encounter, please raise your hand now. *Fervent hand-raising with a sad face* Keep in mind that all of my complaints are based on Heroic mode. I probably would be bald from ripping out my hair if I had tried to play on Legendary.  Ok I think those are all of things that I didn't like. Moving on to the good .
 
 I DID like the story quite a bit. Everyone had pretty epic deaths. Oh wait, except for Kat. It almost seemed like they wasted all their creative juices on making awesome deaths for everyone else and then just said f*** it. Running into unknown snipers is good enough. I won't judge though, because maybe some people thought it had a deeper meaning? The jetpack was a pretty neat addition to the game even though I only used it for the one portion of the game where it was required.  Actually the only thing I ever used was Run, which was a welcome addition to the game.
 
Well I suppose I'll play the multiplayer for an hour or two before putting this game to bed.

I still havent completed this game, got to the part with the helicopter things and the skyscrapers and i got bored.... 
I doubt i'll ever be botherd to complete it.

Definitely jump into the multiplayer because it's a massive part of what makes up the game, you'll get a lot more opportunities to play with the armor abilities, and in my opinion it's very high quality stuff. I loved Halo: Reach but one of the issues with the single player was that as the game neared the end, it seemed like the story was really trying to build up a sense of excitement and urgency but the simultaneous ramp-up in difficulty meant that gameplay-wise things slowed down rather severely. In general though I don't like playing the harder modes in most games as I feel it hurts the pacing anyway.

If all you ever planned to do was beat the campaign and then play a couple hours of multi-player, I honestly have no idea why you bought your own copy of the game instead of just asking to borrow mine. I mean, seriously: my copy has been sitting right here, unused, the entire time that you've been playing yours!

psst. I borrowed jmoney's copy.

Couldnt have said "Spoilers" in the title could you? ruined the fucking campaign for me,
Thanks dickwad

There's an option to switch your difficulty in-game. There's no shame in bumping it down if you're not skilled enough...

i think its just ironic that majority of posts are all 360 faggers on a halo thread

Halo Reach > all the games

Hm. I didn't have much trouble and I played it on legendary. But it's all about knowing what combos of weapons to use and I've built that by experience with all the other games. 
 
My major gripe with it is the voice acting.  It just felt rather disjointed and bland to me for some reason.  Anyone else feel that way?  Not saying I still didn't enjoy it and get into the story, I definitely did.
