Must have PC games

[RooftopAssassin]

-Age Of Empires I, II, and III
-Any of the Total War games
-Civilization IV
-Portal
-Team Fortress 2
-Half life series
-Fallout 3
-Tropico 3

 

[Dirty Apple]

I don't wanna repeat the obvious ones that have already been mentioned. Here are my fallbacks which never fail to amuse:

Neverwinter Nights (more mods and add-ons than you'll ever play)
Call of Duty: Modern Warfare (multi-player is a wonderfull diversion)
Dawn of War (hours in army painting alone)

As an aside, here are some less popular but equally fun games:

Tropico (ever want to be the dictator of a small island country?)
Moonbase Commander (awesome mix tactics and skill)
Freedom Force (fun, silly, camp, and as deep strtegically as you want it to be)

 

[esperandote]

Max Payne
GTA 3
Metal Gear Solid 2
Silent Hill 2

Those are the ones that I have :/

 

[OneStrikeOut]

I would go for anything that really captivated me, regardless of genres.
I usually give up instantly if the game does not get me from the start,
so these games might not be the run of the mill mindblowingly good games.
But any game that I feel compelled to finish deserves a spot on my list.

Abe's odyssey/exodus
Grim fandango
Fallout 1 and 2
Sid Meier's Alpha Centauri
Master of Orion II: Battle at Antares
System Shock 1 and 2
Farcry
KotOR
Sins of a Solar Empire
Planescape Torment
X-wing vs Tie Fighter
Nethack
AvP 1 and 2

And for games that don't really have an ending.

World of Warcraft
Heroes of Newerth, prefferably DotA but that's a mod so meh.
Team Fortress 2
Wesnoth
Dwarf Fortress

 

[kannibus]

A kickass RPG, Biowared if possible. Epic strategy game, Starcraft/Command and Conquer/Supreme Commander styled. An FPS to demonstrate the superiority of mouse keyboard. Perhaps a fightsim if you find one.

 

[Lordmarkus]

Erm...STALKER, System Shock 2, Half Life 2, DOOM, Quake, Unreal Tournament 2004, Serious Sam II, The Longest Journey, Grim Fandango, Silent Hunter III, Il-2 Sturmovik, Freelancer, X3 Reunion, Elite, Elite II, Privateer, Galactic Civilizations II, Hearts Of Iron II, Empire: Total War, Hidden and Dangerous II, Killing Floor, Neverwinter Nights, Baldurs gate 1+2, and some others I can't think of.

I take this mans choices (just because it's him) and add:

- Deus Ex
- Fallout
- System Shock (The first game make you at least enjoy it without having the difficulty ripping your balls of.)
- Thief
- Planescape: Torment
- Outcast
- Duke Nukem 3D
- World in Conflict
- Company of Heroes
- Crysis

 

[Shadow XXVII]

Any Bioware RPG.

 

[NickIsCool]

The Orange Box
Rome - Total War
Crysis (Because it's a game in it's own right and everyone should treat it so, it's a crap-load better than anything from the CoD series, and prettier too - it doesn't need a mammoth to run and I die a little inside every time someone suggests it's only useful as a benchmarking tool. *sniff*)

I err... Just a quick edit there.

It just makes me so damn angry!

i totally agree with you

i find it to be one of the most fun shooters iv ever played. it feels like the spiritual successor to FarCry series from consoles (Not FarCry 2). im not saying FarCry 2 was bad, it just didnt feel like the same kind of game. it should have been marketed as a new ip RUNNING in the cryengine...

OT: lets see...

Crysis
FarCry 2
Left 4 Dead
Doom 3
Battlefield 2142, the last great PC Battlefield game (Bad Company 2 is good, but i want my 64 players damnit >.< )
Team Fortress 2
Shattered Horizon
Dragon Age: Origins
Audiosurf
Dead Space
GTA IV
World Of Goo

And of course
UFO: Enemy Unknown (aka X-Com: UFO Defense)


i feel like im leavin some out... oh well, here is a bunch anyways

EDIT: HOLY FUUUUUUU- forgot to put Max Payne

EDIT 2: and Second Sight

 

[Andrewd96]

Any age of empires/mythology except from number 3 it is complete crap compared to the rest

Edit: Most Sid Meier's games there mostly awesome
