A better story? Saved data being carried over from original? More enemy variety? More out of this world type weapons? Better competitive multiplayer?
Id like to see some sort of save data being carried going on so you can keep all your cool weapons, maybe you could have your level 50 guy to start but all the enemies are already level 50 and the cap is raised signifacantly

" @Pie: I'm going to go ahead and go on record and predict DLC that raises the level cap above 50 and changes the skill trees, a la World of Warcraft. "

Require better reliance on tactics. Also better AI.
 
Strafing and firing repeatedly gets old.

MORE GUNS!

Personally,  I think the skill trees could've been better. Less stat increase mods and more unique ones (like Brick's dashing punch). Also, I think WoW got it right when they end trees with a single-point badass talent. Finally making it to the end of your tree and then having to wait four more levels makes the achievement feel less awesome.
 
Also, silenced weapons and some optional stealth mechanics would be cool.

better character customization.  I want armor, dammit!

Make it play more like Stalker.

" Make it more like Stalker. "

Less Claptrap dancing, too. Maybe once every hour, you play that "Ooh c'mon, get down," but no more.

I have beef @Pie said:

" @MB said:

Id love to see them change up the skill trees a bit, maybe they could throw in a new character just so you can play through the game again with a new guy "

more story and talking characters.. more people in the world/ cities that are not trying to always kill you.

 I wonder what the story will be about, maybe it will be set two hundred years into the future and it will have patrica tannis's great great great great grand daughter, on the other hand maybe not.....I'd love to actually be able to go into the vault this time though..(it is an actual place right?)

Hmm... how about an in-depth story. I thought they had the basis for what could've been a really sweet story, it just didn't seem finished or something...
Maybe some competetive online with some sweet maps based on the single player campaign would be sweet. New features added to new guns and a larger variety of enemies would be sweet too.
 
They also need to fix up the frame rate in some parts, and the AI is pretty crap for enemies stuck in corners etc. 
Harder bosses would be sweet too. If they could incorporate them into the story as well that'd be good. So it's not just like "There's this dude called 9 Toes, we need you to kill him. GO!"

more and bigger environments, and id probably enjoy a realistic graphic style more than the one it has now

A better story and armor. If they make a sequel what will be the selling point?

 A better solution for PC online play. Pretty much busted at the moment.  (You need to go through hoops to get it working.)

Though I suppose they'll probably fix the issue with a patch.
 
Hopefully...
 

Story doesn't matter much in this game, and I like the fact that I'm just exploring, shooting and looting without any hassle. No down time what-so-ever.
 
An actual character customization as well as armor would be nice. Shields are essentially armor, and they could have made them into outfits, if they had the time.
 
A sequel definitely cannot be in another desert environment. It would be hard to distinguish it from this game. More diverse settings would make this game all the better.
 
And better trade and loot options for MP, we aren't in the first Diablo era anymore.

Trade interface.  Matchmaking when you enter the arena.
 
That's it really.

"How bout all of those things plus a great marketplace/trading system? "

• The frame rate on consoles needs to be addressed, first and foremost.
• A trading system needs to be established, as well as a "need-or-greed" system.
• Four-man vehicles!
• Fewer trash drops.

i want horde mode

A trade mechanic.

For a sequel I would like a Sci-fi like city to play in. Any DLC would be good, Actually having armour would be cool too.

" @epilepsy: They have said that they want this to be a trilogy "

" @End_Boss: I want horde/nazi zombie/survival/throw endless enemies that drop good loot mode. "

- A third person mode
- More customizable character, aesthetically speaking, perhaps armor.
- Trading system

A lightsaber penis.

Why would you reference no more heroes here? "

Tons of high level content, more classes. More guns.
 
MOREEEEEEEEEEEE

" a cow level? "

I personally would like the option of either horizontal or vertical split-screen. While I have gotten used to the vertical split-screen in this game, it just doesn't seem to make sense to me why that was the view of choice and not horizontal. It's annoying when I go into the menu and have to constantly adjust the menu's location on my screen so that I can see everything.

I'd like more environments, maybe a good city one with a population that you have to deal with. Give the red necks a rest.
 
I'd also like more character classes. Another cool thing would be skills you can kind of combine with other class skills across classes.

* Trading Interface  
* More skilltree options 
* Crafting (building my own guns would be a lot of fun) 
* Storage in a town/house/something to be able to store more loot 
* More enemy variety 
 
All criticisms aside, this game is a ton of fun.

Anyone say randomized boss loot?  I'm all for more boss runs and less New Haven chest opening parties.

More weapon manufacturers, equippable armor (just a chest piece and possibly helmet, no need to get too in-depth), better ui (pc version), better ai, better online system (use steam please).
 
Basically, more of everything with a fixing up of the first game's flaws.

• I'd like it if I could cycle through all my quests while still on the map screen.  That way I can see what quests are located near each other.  As it stands today, I have to move to the quest screen, select a quest to track, then return to the map screen to see where I need to search to complete it.  I'd be easier if while the map screen was open I could click the d-pad to select a quest to track and then pop back and forth between a few revealing where all waypoints are located.
• I'd like to have a tab that organizes all my non-equipped items organized by sell-price.   I'm always picking up weapons and items for sale later, but when I hit the max I can carry I need to drop the cheapest one for a newly discovered better item.  I then have to cycle through all the stuff until I find something I think is the lowest sell-priced item I am carrying.  It would just make things faster.
• Either improve the jumping or get rid of the jumping puzzles.  I don't completely hate them but they feel floaty.  Hunting down weapons parts often means traversing up to weird heights. 
  
• Maybe this isn't in the PC version, but last night I noticed that when cars drive through water they leave no wake.  I didn't notice at first, but now it is glaringly obvious to me. 
  
• Movement for the NPCs...really, all of them just stand there like statues.  This game needs some Fable 2-like life for the people.
  
• [Obligatory] More varied enemies, better (some!) story.
• Some sort of reminder/persistent alert when new quests are opened in other regions you've previously visited.   Sometimes I can't remember where or when the droid tells me that new quests are available in some town.  I'd just like a box in the corner that says "Blank says he has new quests for the vault hunter"
• The ability to change the difficulty mid-game.   All my quests are green or gray.  I'd like to find some harder ones, but I'm just following the quest path before me.  If I could change the difficulty for the gray ones, it might make those less of a chore.  

More variety in the environment and enemies, a story that makes some kind of sense. The ending did nothing but confuse even more, just by not telling you anything.

And let me set more than one active quest diamond. In the gather log quest it would be nice to see where they all where so you could pick them up in the order you choose.
Also since I'm playing on computer,  making the UI a bit more intuitive for mouse use would be very nice.

A story.
