First steam game?

Def Garry's Mod, i remember watching youtubers playing prop hunt and zombie survival and i wanted to do that myself

HL2 + CSS + DoD from a CD disk. This was nice time

TF2 was my first, and I bought GMOD first. I have a lot of hours on both of those.

As far as I can remember TF2 but the first game I bought was I think terraria.

My first Steam game was TF2. From there it went to Portal 2, then Terraria, then CS:GO, then GMod, then CS:S, and lots more after that.

First game? damm... its Saints row the third.. good old days.. :D

For me its got to be terraria and I spent 400 hours before stopping on that game.

i just had to look this up, mine was actually torchlight 2 and that was roughly 5 years ago ^^

Killing Floor is my first paid game.... Played some demos before

My first steam games was Counter Strike Offensive.
