Next Half-Life.
BlackMesa (ok it’s not a “game” but i’ll backflip to death, i’m already training for that day!)
A DLC for Portal 2 with Rat Man involved. :aah:
Alien Swarm 2. (ok, it’s nearly impossible, but i’d like it.)
A new GTA like San Andreas, fun to play and to mod.
Beyond all the obvious titles which have already been said, a true sequel to Red Faction would be pretty cool.
The same goes for Tiberium Sun.
EDIT: Goddamnit, someone just mentions BMS as i write this post, and totally ruins the joke.
SWAT 5 (I enjoyed the crap out of 4, now I’m too familiar with the maps)
Hl2:Ep3 obviously
GTA5, as long as it has more variety in the map. Not just city, but also nature (like GTA:SA, doesn’t need to be in San Andreas though)
Command & Conquer: Generals 2 (it’s the only game of C&C I like. RA2 I like too, but that’s merely because it’s one of the first games I ever played)
That’s about it I guess.
The word! Though not possible. I think this series is long time now fucked up beyond redemption.
Rayman 4
Oddworld. Any Oddworld game.
And the next GTA.
Generals 2/A C&C 5 that will retcon C&C 4/Renegade 2
A new Wing Commander game, HomeWorld 3, Black and White 3 and some info on MechWarrior 5 and STALKER 2 would be nice.
Great suggestions everyone! Lot’a good ones.
Just throwing this out there, I’d also like to see a sequel to Conker’s Bad Fur Day made. My 3D Platformer itch needs-a-scratchin’.
Quake 5… WITH GOD DAMNED BETTER MULITPLAYER THAN 4. Preferably as good as 3. (Don’t want the exact same though.)
Big Rigs 2: Modern Trucking
actually Homeworld 3 seems like a better idea
Empire Earth 4, but with the gameplay style of Empire Earth 1.
I would probably do multiple backflips if they make FS3 :jizz:
Left 4 dead 3.
Portal 3
Half-Life 3
STALKER 2 (MOAR INFO!!1)
Left 4 Dead 3
Cold Winter in HD (Loved that game)
Crysis 3
GTA5
:awesome:
Dungeon Keeper 3, I loved both DK and DK2 was gutted when ea brought bullfrog and cancelled it, still i can dream
HL2: Episode 3
XCOM inspired game- Made by Valve
A SimTower inspired game, in 3D
Imperium Galatica 3 - Was IG2 like the only 4x game were you could buy second hand ships rather than making new ones? “Fear my ever expanding flotilla of half-arsed ships purchased for shit, put together with duct tape and can lose hull integrity by just tapping on the hull”
Epic 40,000 - In the World in Conflict engine
Another Space RTS by Relic - Homeworld was one game that I fell in love with
Dungeon Keeper 3- Yeah spleenite, we can always hope 
Sim City 5- CitiesXL was alright but not indepth enough
Mount and Blade: Post Apocalyptica - Tanks with water cannons Vs Camels with Machineguns
also valve can’t count to three
Descent 4
Well, all we’ve got is that an interviewer asked about the futuristic battlefield in Frostbite 2.0, and the devs went “yeah, sounds good… hmmm”
another game with 3 million leaked valid CD keys
