What was your first Steam Purchase?

retail, Cs:s with HL2:DM, HL2:LC and DoD:S. digital, TF2

LOL, I have 144 games and none of them are purchased.

Making History: The Calm the Storm - Retail 1st
Red Orchestra Franchise Pack (ROW) - Steam Store 2nd

Orange Box as retail. Was the best gaming decision in years. Had no interest in Steam before that. Oh, and it was quite late, Christmas 2011 actually lol

l4d + l4d2 =)

Bought Half-Life 2 on release back in 2004

Crusader Kings II in April. Followed shortly by Company of Heroes, Fate of Atlantis and Legacy of Rome DLC

Torchlight 2 at 15 bucks. And I REGRET THAT PURCHASE!

Not a game worthy of my 15 bucks. 3.5 bucks maybe.

I purchased Psychonauts when it was on sale for $2 in 2010. I then ignored my Steam account completely for over a year, not even playing Psychonauts. Some other games came up for sale, I bought them, then I realized that Steam would be a great thing to actually use to store my HiB games.

Half-Life 2 ofcourse!

Dota 2 Treasure Keys.

Football Manager 2013

Terraria!

Dead space 1 and 2

Left 4 Dead 2 (on this account).

went in on Half-life 2 with my brother at launch (2004) but he took the account when I went back to school after the summer.

First one on my account was Braid and I kept the avatar ever since

CS 1.6 in 2009 I guess.

CS:S, it came with other games too though.. like HL2/HL2:DM/DOD:S

Portal 2

none got all my games for free , but still waiting to win a game from this site

TF2 when you still had to pay for it!

Deus Ex: Human Revolution

Fortix! For ME! dum dum dum

Never bought on Steam, I get my games elsewhere.
