Has to be HL2. I remember being annoyed that I had to download some buggy program that took forever to load in order to slay some Combine. The sick and twisted saga began.

Counter Strike :)

Trials 2.

Half Life 2... i was not very happy that when i installed this wonderful game i had to instal a bad program like "steam". then after i beat the game about 4 times i was even more mad to find out i couldnt launch the console in HL2 to do some cheats... i uninstalled HL2 and this "steam" program... i still actually havnt played HL2 since then, but now im almost addicted to steam... idk what happened that i changed my mind... Empire Total War maybe? yea... i hated steam so much that it was that long since i installed the program. i even avoided games in stores that said u needed steam. but today is a different story

Terraria. It was what got me into Steam.

Tobe's Vertical Adventure. It was the cheapest thing I could find at the time and I wanted to add friends on Steam.

Call Of Duty: Modern Warfare 2

I bought a hard copy of half-life, which also gave me both of the episodes to it, day of defeat, counter strike, team fortress classic, and ricochet for some reason.
