What was YOUR first game you got on steam? Small GA added.

I wasn't really surprised myself since the games listed were Counter Strike Source, Day of Defeat Source. These were the first games that I purchased since I remember with either money I got from Christmas/Birthday I purchased the double pack that included both CSS and DODS. I remember then buying HL2 shortly after that... since I remember I needed/wanted it so I could play the different mods, since most mods required hl2 base.

But if you are talking the first game I actually bought from steam, then that would be HL2 - but HL2 wasn't listed on that list for qualifying games.

FINAL FANTASY XIV: A Realm Reborn CE

Total War: Shogun 2

it was Enclave https://store.steampowered.com/app/253980/Enclave/

Super Meat Boy, game that made me create a Steam account and stop pirating games 7.5 years ago. Still one of my all time favorites.

Orange box

Civ 5 ^^

Torchlight and Torchlight 2. I did preorder that TL2 thinking it was a Diablo fix. Turned out I was wrong -- felt robbed up to this day.

Actually less embarrassed than expected. My first purchase was 3 games at once for $22:
Last Dream: an rpgmaker game actually worth the money, lots of effort put into it and a huge world to compulsively explore. It struck that nostalgic chord of the original Final Fantasy style JRPG
FATE: Classic dungeon crawler, oh god the nostagia of this purchase is too much to handle
Long Live The Queen: One of my favorite buys of all time. One of the hardest games I've ever played. You get to repeatedly murder a princess over tiny ass mistakes in talent distrubution. I spent a week huddled over it like a crazy person and that pink haired child didn't live once. RIP Elodie, you live on in my heart.

Papers Please.

Space Rangers 2: Reboot.

team fortress 2

KILLING FLOOR 1 IN 2010..

Skyrim

Spellforce Complete, only bought it because my bro wanted to chat with me on Steam, and I needed to make a Steam account anyway because I wanted Skyrim on PC... (I bought it during the winter sale 2012, had it on 360 on release (wife still wasn't converted to PC back then, so I had no choice...)
To soften my surrender to Steam, he gave me Counter Strike: Source and The next BIG thing...

Little Farm, a simple casual puzzle game that I played again yesterday because Steam reminded me about it ^^

NBA 2k9 and i was livid that i had to install some stupid DRM service called steam to play it. Even worse i had to download most of the game which took all night. How times have changed...

My first was GTA IV + LCS and i never forgot because it's a thing to be proud of!

Oh, i played it hard back then...

Looks like my first ever was Magicka but I couldn't play it back then and then never got around to playing it since I was still playing a lot of console games back then. I think the first game I actually played was Terraria.

Mine was the exact same as yours! I'm actually in the process of installing (downloading) it for the Spring Cleaning event.;)

Counter Strike Anthology, basically classic cs&friends(but not tf classic for some reason). I took it borrowed from a friend, and we both didn't know that I had to create an account for it and that I would be stuck with that game forever. Needless to say I never returned the game :p
He never asked back also so it's his fault.

But now he has family sharing linked to my account, so I guess that counts.

The reason i started using Steam: Dota2.
