Games of the 90s, Id Software and Thief

I grew up playing games in the 1990's. I was introduced thanks to my father who was really into computers and used to work for Dell. I've played Doom and Quake, as well as Wolfenstein 3d and other classics like Blake Stone and Shadow Warrior. Id, the creator's of Doom and Quake, just recently released an interesting infographic on the history of their company, seen on the gaming website GameFront here. The great thing about Doom was that it ushered in the age of modding. Players could build their own levels and content for doom and release them in packages called "wads." However, the game I cherish the most from the 1990's is Thief: The Dark Project. Having played it, as well as it's re-released expanded edition Thief: Gold, I loved the story, the atmosphere, the level of immersion the game gave you through AI conversations and books that you'd find in you travels of each mission. What really made it stand apart from other games of the 90's in my opinion was it's focus on compelling story and immersion not quite seen anywhere else. Sure there was Metal Gear Solid (which I like as well), but Thief has actually been credited with making the stealth genre what it is today. If there was no Thief, there would be no Splinter Cells or Hitmans most likely.
