First Steam purchase?

My first game on steam is garrys mod i have about 1,000 hours on it

This is sad but I'm pretty sure it was TF2 before they made it free. I'm pretty sure I bought it like, less than a year before that was done too.

My first Steam purchase was the original Don't Starve about 6 or 7 years ago. Have about 80 hours on it, along with all of the DLCs. Moved onto Don't Starve Together after its beta came out. I've moved on from the series, but I still think they're great and intuitive survival games.

My first steam purchase would have been counter strike source and still good to this day!

The first game i bought on steam was Empire Total War. And i regret it every day. Was by far the worse total war ever made.

Marvel LEGO Avengers. Honestly, I have utterly no regrets about it. (Portal was my first Steam game, but that one was free!)

First game I ever bought was Garry's Mod in 2011, but I had a steam account for a few years prior

my first game that i bought was Primal Carnage haha in 2013 lol

portal 2 but it was from game stop. i expected a disk inside but just got a steam code

as i remember my first steam per was cs go i was really enjoying it then
