Ok so :

Ghost Masters 2 (good but clumsy game, could be refined and expanded)
Evil Genius 2 (good but clumsy game, could be refined and expanded)
Undying 2 (great game, unresolved cliffhanger)
XIII 2 (great game, unresolved cliffhanger)
Manhunter 3 (great game, unresolved cliffhanger)
Heroes of annihilated empires 2 ("scifi vs fantasy" postulate left for sequels)
Populous 3/4 (deserves modernised populous with original gameplay)
NOLF 3 (more nolf would always be good)
Subwar 2051 (we need more underwater-feeling scifi subsims, at least another one)
Gabriel Knight 4
Portal 3 (more portal would also be good)
Indiana Jones and the whatever of the whatever (a new emperor's tomb-like 3d indy would be nice)
Outlaws 2 (some cartoonish leone-inspired cell-shaded open map old west fps would be welcome aswell)

and also, hmm...

Warcraft 4 - most likely never going to happen

Lost Vikings 3 - most definately not going to happen, unless Blizzard figures out a way to make into a some kind of f2p online thing with microtransactions.

Alan Wake 2 - that one I want the most, but it won't happen any time soon, if ever

Legend of Grimrock 3- Finally something that migh happen in near future. The first two were great, so kkep them coming.

Mark of the Ninja 2- I have no idea what the chances are

Monkey Island 6 - More Guybrush! More fine leather jackets! More three-headed monkeys!

Deponia 4- I'm sure there is more to see and do and break and mess up in the world of Deponia.

SWAT 5 and Bulletstorm 2- my favourite FPS games, the best from both ends of the spectrum: the tactical and demanding, and the balls-out action and fun.

Dungeon Keeper 3, obviously.

Darksiders 3, obviously.

The Suffering 3, obviously.

A Vampire Bloodlines sequel, this is in dire need and badly, like right NOW!

A Sid Meier's Pirates Enhanced Edition/Remake/HD.

Diablo 3 the aplha, deleted version.

GTA, end of the HD era, reboot with 3D era's style, gameplay and game mechanics.

Dungeon Keepers
Evil Genius
Gangsters
Halfway
Arcanium
Kingpin

Hmm, I missed this thread somehow.

I'd like to see (assuming they are handled well and not in that way devs have that tendency to screw new old games up):

Vietcong 3
Men of Valor 2
Battlefield Vietnam 2 (with an actual Battlefield instant action)
Unreal 3
Quake 5 (in the Strogg vein or the Quake 1 vein, it matters little)
STALKER 2
Men of War 2
Mighty Switch Force! 3
Aliens vs Predator 3 (or 2 if 2010 was a reboot... or is it 4...)
Battlefield Bad Company 3
Ace Combat 7 (yup, in Strangereal, please. Fighting Russians is only so fun especially after the hundredth time. Belkans are cool.)
Medal of Honor: Pacific Assault 2
Super Mario Sunshine 2
Aliens Infestation 2 (I think this would benefit on the 3DS or PSV or both preferably)
Fallout 2 could use a sequel while I'm at it (I kid... sorta. I would like an isometric game with better graphics and more crap to do)
(I was gonna say Delta Force but Angel Falls was announced, it's just never gonna come out)
Red Steel 3 (after playing Shadow Warrior 2013 I think the world could use another one of these)
The Conduit 3 (I can see why no one else would want this, but 2 was funny it just needed fewer bugs)
Age of Mythology 2
Arcanum 2
Binary Domain 2 (I would like that anyway)
Yakuza Dead Souls 2 (ditto)
Baten Kaitos (from a ridiculously long subtitle to a single worded subtitle, now to none at all)
The Last Story (in the vein of, but not a real sequel)
Two Worlds 3 (why not)

Edit: A nice proper single player Dragon's Dogma would be really cool too.

I'd love to see a sequel to Aquaria. Years ago I imagined it might be created and named Terraria (followed be Aeria, or vice versa), but that name's thoroughly taken now.

Those are all pretty good, especially Vanquish 2 would be nice. Although, I think you meant Mikami.

- Eye of the beholder 4 (Hoping Bards Tale IV will be good)
- Monkey Island 5 (By Tim Schafer / Ron Gilbert / Dave Grossman, please :)
- Last Ninja 4

I'd buy several copies of these in an instant, no matter the price :)

Oh crap, Mikami, of course. *goes to the corner with a dunce cap*

It's okay, you knew Vanquish. You get the gold dunce cap at least. *replaces the dunce cap with yellow construction paper dunce cap that reads "6oLd" on the side*

Age of Empires 4- Could happen, HD reboot of Aoe 2 revived interest and a while back there was apparently there was a job advertised to work on "an entry in a well loved strategy franchise" (Or something like that.)

Dawn of War 3- Could happen, Sega are on good terms with Games workshop otherwise Total War: Warhammer wouldn't exist, Relic are probably nearing the end of their development of Company of Heroes 2

Kotor 3- Could happen probably after the new Mass Effect if it happens (Would be probably be developed by Bioware.).

Supreme Commander 3- Never going to happen unfortunately
