For some reason my purchase history doesn’t go as far back as my Steam account. I had already redeemed some of my Half-Life keys in Steam when it first came out, but my first purchase was the Half-Life 2 Gold steam release, which included:
Half-Life 2*, Counter-Strike: Source, Half-Life: Source*, Day of Defeat: Source*, Valve’s back catalog currently available on Steam, Complete Strategy Guide from Prima Games, three different Half-Life 2 posters, Half-Life 2 hat, Half-Life 2 postcard, Half-Life 2 stickers, Half-Life 2 Soundtrack CD, and a chance to win a trip to Valve (one trip offered for every 5000 Gold packages purchased).
*Available upon product’s release.
Way back in 2004.
