Continue of my top 50 pc games of all time after I was interrupted by a rage post.

30. Battlefield 1942 (2002)
-developer: Dice
The FPS genre is flooded on the PC and especially the WWII themed ones, and I have to say we can all thank EA for that. Battlefield 2 was certainly miles better than the original but battlefield 1942 is the game that started this WWII frenzy. It wasn't just another FPS back in the day with mindless killing in an arena styled map but this game had large open maps with two factions involving various vehicles ranging from jeeps to tanks, even aircraft. Playing in a real landmark from WWII in a objective based multiplayer mode made you feel like your victory meant something in a historical setting.

29. Ultima Online (1997)
-developer: Origin Systems
So this is where it all started, Ultima online officially opened the door to a land known as Massive Multiplayer Online Role Playing Game. It was based on the expensive fantasy world that was in the previous Ultima games. To many extend this game is very much like the modern MMORPGs that it had a monthly fee structure, thousands of players were playing in the same open world from a game server, there was a player vs enemy and player vs player combat structure, and the online community is monitors by whats called Game Masters. So all the MMOs today can thank Ultima online for making them billions.

28. Age of Empires (1997)
-developer: Ensemble Studio
Like many other RTS on this list, game play wise Age of Empires does not strait away from the basic RTS element but what make it different is that it also had that simulation element built in the game. You are not only building your resources and units just to win that round or that map but you are also building your empire. As the game progresses you the king or emperor will conquer more and more land, and it is up to you to successfully rule your entire empire. It also had different time periods in history thus adding another element to the game play.

27. The Elder Scrolls 3: Morrowind (2002)
-developer: Bethesda Game Studio
Bethesda always had their special way of doing an RPG like Bioware. They seem to aim in creating the biggest world possible and allow you to roam the world as you see fit, and Morrowind was no different. Although Technically Morrowind was a much smaller world than their previous work Daggerfall but Morrowind improved on just about everything. The world felt much more livelier with bigger variety in the NPCs, and the combat along with the story of the game was much better as well. Although Bethesda was never known for well structured quests and story telling in their games, Morrowind was probably their best attempt as one of the most rich RPG experience at the time.

26. Star Wars: Knights of the Old Republic (2003)
-developer: Bioware
It was not the first time Bioware ported or developed a game for the console but this is the game that made them a household name. Possibly the best game using the Star Wars license Bioware stayed true to their nature, crafting a completely new and original Star Wars Universe that complete different from the movies and yet believable to the fans. The world of Kotor was big and expensive with many many unique characters, and it was said that there were enough dialog to fill 2 novels. It was a game that made you wish Bioware writers did the Star Wars prequel trilogy instead of George Lucas, and it had everything that is great about Star Wars and a Bioware game.

25. Counter Strike (1999)
-developer: ???/valve
The only game on this list that is not even a proper game. It all started as a Mod to one of the greatest FPS ever then realizing the popularity of this Mod, Valve promptly bought the rights to it. Counter Strike continues to be one of the most played online FPS ever and is used in many competition as a measuring stick for someone's mad skills. It also did a number for future team based tactical shooters and more mods for Valve developed Half Life.

24. Rome: Total War (2003)
-developer: The Creative Assembly
From a handful of soldiers to international diplomacy and everything in between: Total War has always done scale brilliantly. Rome is the series' peak. Successfully besieging Rome itself, overcoming its towering walls and charging thousands of men and horses through its streets is one of PC gaming's sweetest moments. Endless hours of sweating over the strategy map pay off on the battlefield in spectacular style.

23. System Shock 2 (1999)
-developer: Looking Glass Studio
"Hurry, run!" - words that still send a chill down the spine of anyone who's played the scariest FPS/RPG ever made. It was the urgent groan of the pipe-wielding zombies who roamed the corridors of the huge spaceship Von Braun - just before they clubbed you to death. They were warning you about themselves. Somewhere inside there was a helpless human being, aware of the atrocity it was about to commit. This is a game to play if you wonder where Bioshock came from.

22. Thief 2 (2000)
-developer: Looking Glass Studio
When you think of great PC games of the past a lot of FPS, RPG and RTS will pop in your head. Those genres make up majority of PC games but every once awhile a different type of game like Thief makes you say this game is awesome. When ask about the great stealth games to today's console kids they will likely say that either Metal Gear Solid or Splinter Cell is the best stealth game and that's when you laugh at them by showing them a picture of Thief 2, as well as educating them on why PC gamers are like glorious master race and console gamers are like dirty peasants.

21. Doom (1993)
-developer: ID software
The father of all modern FPS. Doom started it all with the first person gun view, the 3D game play, the networked multiplayers and eventually the modification of a game. designer John Carmack won a life time achievement award for making this game as most his later works with ID software are pretty much the same plotless, mindless shooters. I have also heard that all the bitches want him for that he is the creator of doom, could be just a rumor though. Doom can also be used as a trivia question as many of the console generations today thinks Halo is the first ever FPS made.
