There is not much to specify for the question, its really simple: Which title is the first game you have purchased on Steam? Was it a good decision? How much did you pay? When was it and what device? You don’t have to answer all questions, this is just a fun discussion to have.
You can check your history: https://store.steampowered.com/account/history/ Edit: Some in the comments pointed out that the purchase history doesn’t go back all to the beginnings of Steam. So if you purchased something earlier, it won’t be listed on your account.
(I reply with my game too.)


My first game on Steam was Counter Strike, but I had already been playing the retail release for a while. They had some one-time activation to bring over your CD key. When they launched Steam, it was horrible. Remember, this was the time of single core processors (Pentium 4), so any anything that interrupted the cpu would effect your FPS. Plus it was buggy and crashed all the time.
I boycotted Steam and Valve and kept playing pre-steam CS 1.6 till the Orange Box came out. But TF2, Portal, and HL2 plus episode 1 was too good of a deal to pass up, and I had a new AMD Athlon that felt like a beast at the time.
Kinda sad I forgot my original account, would have been neat to have an account as old as Steam. Oh well.
Same here, CounterStrike, and also lost my original account. Don’t even know which email it used, my work account at the time (borged at least twice since then), or one of four ISPs I went through around then.
Oh you are one of the OGs too. Well you did (rightfully so) boycott Steam in the beginning and didn’t care for your account anymore. So yeah, that’s unfortunate. But well, its the past anyway. :-)
