You know, HL2 was one of the first games I ever preordered. I went to Gamestop in August 2003 to preorder it, so excited to have such a graphical powerhouse on my PC in less than a month.

I had that receipt in my wallet for over a year. Barely legible, they still honored it. Then I found out that it required Steam, and I didn't even have to have a box at all.

I later sold that box at a yard sale, to find out a year later that it was still tied to my Steam Account, and I had sold them what amounts to an empty box.

All that, and I don't think I've actually beaten it without cheating. Heck, I don't think I've beat HL1 without cheating either. Too easy to cheat on PC games, I can't resist.
