What was your first game on steam? GA ended.

It was Counter Strike 1.6.

Infact, CS made me use steam. I was pirating stuff before. Now I actually support the devs for the games I play and Legally get free stuff once in a while as well. Self satisfaction is an awesome thing

The Sims 3 which I played on Origin. I had problems with the download and Steam support gave me unrelated answers. I posted on the forum about my issue and someone pointed me to Origin. I had the same problem, but it got solved within minutes of chatting.
I only came back to steam because my old Final Fantasy 8 copy didn't work anymore.

Bought the acc with Modern Warfare on it.

Metro 2033!

Half-Life 2 Deathmatch from an old promo where it was free (6th August 2009 according to Steam). The first one I bought was Fable The Lost Chapters

Left 4 Dead 2

TF2... but the first game i bought was wargame: red dragon i think

Well, Half-Life Platinum Pack over 12 years ago

iBomber Defense Pacific ... it was free, my next game was free too (Anomaly Korea). It was only after then that my wallet took a hit

According to https://store.steampowered.com/account/licenses/ my first was the very first Wolfire Humble Indie Bundle which included:

Aquaria
Gish
Lugaru HD
Penumbra: Overture
Samorost 2
World of Goo

I had used them on Linux and one day was playing with WINE and decided to try to run Steam in WINE and activate the key from Humble Bundle :)

The Walking Dead, bought it together with Awesomenauts, but walking dead shows first.

Ah, ToME... the very reason I really started with Steam was because my brother was playing it so much, and it looked seriously awesome. One of my most-played games!

Metro 2033

My first free game was Dota 2 and the first one that I paid for was Payday 2

Ghost Master. ayy.

Jan 17, 2005 Half-Life Platinum Pack Complimentary

Left 4 Dead 2

killing floor 2

killing floor

Spore :)

L.A. Noire Complete Edition. The sad thing is I still haven't played it :(

Second was Bioshock, at least I can say I finished that one.

Might and Magic Heroes 6. Interesting. I never thought this would be the first.

I find all this second account nonsense weird and shady...

Skyrim Legendary Edition September 22th 2013

Thanks to Skyrim!

Ouch, sorry about your old account!

My first and only for a LONG time was Warlock: Master of the Arcane. I put a lot of hours into that one! :D
