Your First Steam Purchase

Dead Pixels.

Half-Life and CS

L4D2 ;)

Orange Box for me, nothing fancy and I only played Portal out of it every now and then for a few years until just recently getting into buying from Steam.

Such fond memories.

RUST

counter strike global offensive

Portal Retail and Half-Life 2: Episode Two Retail, hello from 2008 year :)

portal 1, portal 2, half life 1, half life 2, and the episodes. all in the same purchase

Mine was portal 1 & 2

Civ V. =D I didn't actually buy it, it was a gift. At first I was like "what is this steam crap I need to install?" Then I was lik "=D".

Audiosurf

Ignoring free games and gifts (since I as given a lot of bundles before I got a decent PC to actually run games), Sonic Generations was the first retail disc that activated on Steam, Zeno Clash the first game bought within Steam store.

Fallout New Vegas

Half-Life

Terraria 4-pack. I was the only one with a credit card back then, so I bought it for a group of friends during a sale. They actually paid 1 game each, at the price of the sale, so I got the fourth copy for free :D

Left 4 Dead.

Then Left 4 Dead 2 came with better graphics, new weapons, and everything. And then they started to port everything from the first game to the second.

Well, at least it was a good game.

Defense Grid: The Awakening

In Steam store? DoW2 Retribution then.

Team Fortress 2, back in the days when it wasn't a free to play.
