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.)
That’s basically the reason I bought it. The idea of a random indie game being so easily obtained was novel af in 2003.
It was 2005, but yes
little fun story is, that I was part of a small mod team back then. And by pure chance we were in contact with someone at valve, who told us about the plans of opening up steam to 3rd party games and mods. And our mod was considered to be put as one of the first games to be put into the store. at least for a short time (alas, didn’t work out for… internal reasons. I think mainly because it was a mod and not a full game)
