What GAME series do you wish they bring back?

System Shock
Flashback: The Quest for Identity
Tie Fighter
Wing Commander

-reboot or sequel, I'd take either.
Final Fantasy Tactics

Yeah, FFT was never a series, but give me #2 already damnit.....
Eternal Champions
Diddy Kong Racing
Kingdoms of Amalur (I really liked that game)
Streets of Rage (or Final Fight)
Baldur's Gate
Final Fantasy games similar to the ones prior to #10
Wizards & Warriors
Wing Commander
Wing Commander Privateer (deserves it's own category)
Lords of the Realm
Falcon (flight sim)
Silent Hunter (sub sim)
Baldur's Gate
Command & Conquer: Renegade (sequel by original Westwood ppl plz)
SubSpace (the sequel MMO)
Zone of the Enders (third sequel plz)
Raptor (remastered remake)

Counter-Strike 1.6 :D (what if Source engine never happened?)

Goldeneye (remastered remake w/ original 4-player split screen)
If we're going to remaster a CS version, it has to be 5.2. Quick scoping, actual fast movement, etc.
In no particular order:

MissionForce: Cyberstorm (this desperately needs a remake for the iPad)
Quest for Glory
Unreal Tournament
Quake (of the :III Arena variety)
Wing Commander
X-Wing Series

The thing that really irks me about all the new space combat games coming out is that every single one of them looks like it revolves around the player being basically a space privateer. I want my Wing Commander, where you don't get to pick what your missions are, and you don't have to worry about having enough credits to repair your ship if you take a few hits, but still complete the mission.
NovaLogic's Delta Force , almost everything but BHD sucked....

New game engine, same everything else.

Star Wars Rebellion! Loved it.
Alpha Centauri
Full Throttle
Maniac Mansion/DOTT
Yakuza/Ryu ga Gotoku (English translated)
The Warriors

...and plenty more I'm sure I'm forgetting.
The warriors basically just fix the camera angles and re release the game id play it.
Wing Commander
Knights of the Old Republic (Non-MMO)
SimCity (Pre-EA)
Unreal. Not the tournament game,but the original single player. Unreal 2 sucked,the game deserves a better sequel.
Soldier of Fortune,with the elements that made the first two so good.
Another Godzilla fighter.
M.U.L.E. with 4 joysticks

still to this day have not had more fun

This!!! (Four billion, six-hundred and seventy-million, four-hundred and sixty-two thousand, three-hundred and twelve times!!!!)

Then Ultima and System Shock.
System Shock
A real sequel to Thief II, not an emo reboot
Outcast (too bad the Kickstarter bombed)
Monkey Island
Grim Fandango (can't wait for the Double Fine HD remake)
I can't believe no one has put Generals on the list yet. Its demise was a real letdown after all the hype around it . Bring back "WESTWOOD STUDIOS" to remake all the old C&C games with todays HD tech. I bought an extra copy of the serialized games from Westwood and still have them in un-opened boxes. Half-Life also to finish it out.
Medal of Honor allied assault remake or new addition. Bring back the world war 2 shooter games with the latest graphics and sound effects. 128-1024 players online on one server. ;)

Ah a MOHAA player eh?
Loved that game.

Do you remember alliedassault.com?
Loved the community, the whole atmosphere MOHAA had.

Shoot, I even overplayed the demo in Stalingrad before the retail came out. LOL.

A definite plus one sir.

Also, I was a huge fan for Call of Duty World at War.
Loved the multiplayer on PC.
I don't think I ever owned a game so well then these two mentioned games.
