I had been planning to check out day of defeat today; it said you could start playing it after 6 pm if you had gotten it via steam. I had the gold version of half-life 2 so I figured I’d be good to go. When I tried to run the program, it was acting like I hadn’t bought the game, sending me a link to the page where you’re supposed to buy it. On that page, however, it had a little icon next to the ‘half life 2 gold pack’ saying ‘you’ve already purchased a half-life 2 game package, so you can’t buy another one.’ After restarting steam twice, I figured maybe it was corrupted or something, so I uninstalled it and downloaded it again. When I still had the same problem, I went over to look at my box and realized that I have the ‘collector’s edition’, but not the ‘gold’ edition. So I had to fork over $20. Curses.
Edit:
Damn, that was $20 I just wasted. It was OK, but Call of Duty is much better.
