Day of Defeat on GameFly for $1 gives 8 games

I purchased Day of Defeat on GameFly from Day of Defeat and when I activated it, it showed 8 games:

• Counter-Strike
• Team Fortress Classic
• Day of Defeat
• Deathmatch Classic
• Half-Life: Opposing Forces
• Ricochet
• Half-Life
• Half-Life Blue Shift

I was only missing 3 of those but it added them to my library. Quite a deal for $1 after the MAR20OFF coupon code.

Update: Faraqona pointed out that the key from GameFly seems to be redeeming this package rather than just the single game: Day of Defeat
