What was your first game on steam? GA ended.

Half-Life 2 GOTY edition

Front Mission Evolved, the shame of a great franchise.

Insurgency. Key from HB. 250+hrs now.(OMG HOW MUCH TIME HAVE I WASTED)

Portal, when it was given for free because of "Learning with Portals" in 2011.

L4D2 and it happens to be my favorite. Lucky me.

Interesting. I thought it was Deus Ex: Human Revolution, but turns out it was Tomb Raider and DX was the second. xD

Terraria!

Lol, I had no idea, my very first purchase on steam was batman arkham city goty, which i bought to giveaway here.

I had many games before that, but none purchased from steam itself. The first game I activated on steam was Lucid.

Portal because it came with the PS3 version of Portal 2. I actually had an older account but I've lost access to it. (Forgot PW, and used a school email which is gone.)

Puzzle Pirates! <3333

starbound

Portal

Sanctum 2 ^^

Half-Life 2 with Counter-Strike Source and Day of Defeat Source.
Bought it for the Counter-Strike

Half-Life and Counter-Strike (the mod, circa 2000)

Yep, Orange Box :)

Dota 2 (6,119 hours played) coz its free and playing dota 1 since 10 years old xD ~good game, good game.

Mine was Civ 5 from the greenman gaming giveaway

Portal

My first game was Black Ops 1 but was hacked away :L(My fist account)
For this account, it was outlast that was my first game :O

My first was Star Wars Jedi Knight: Jedi Outcast. Played the hell out of it on PC years ago, but I don't have the disc still q:

Thank you for the party invite! :D Haha.

Half-Life Platinum Pack

because I was already playing Valve games for years before Steam existed.

Left 4 Dead 2

Duels of the Planeswalkers 2013.

Which is funny, because I can't get into Magic for the life of me. This was my buddy's final attempt to get me to play and now I've spiraled down the hole that is Steam :(
