First steam game?

not sure i think it was half life or conter strike or idk, all i remember is half life and some 2d games

my first steam game was CS:S that I bought 8 years ago also got vac banned 2000 days ago on it xd

it was gmod lol, i think i bought it in like 2012 and i was so excited to play it i spent hours playing it

The first game I got on steam was defiantly Garry's Mod.

My first steam game was Counter Strike! love that series a lot!

Fallout 3 would be my first, really wanted to play with mods so i had to play on PC.

it was Rocket League and I had very much fun with my Friends.

Of course Counter Strike 1.6 (i have an old account :D )

Definitelyprison architect got over 120 hours logged in. Such a good game!

I think my first game was CSGO honestly but not sure tbh.
