One of the best values is the 'Half-Life Platinum Collection', which is 5 CDs of which 3 are separate FPS's taking place in a top-secret gov't facility...It's three different games, in the same environment, but as three different characters [scientist; security guard; soldier] with different agendas. Takes some skill, so there's a 'training facility' before you actually enter the game.
Back when I was working full-time, I had barely enough time to check out the various games to see how they played with different hardware (that's the Beta testing); I had no time to get into & enjoy the game itself...These game designers put an amazing amount of detail into the games, along with in-jokes, running gags, and Easter eggs...Now I can finally spend hours/days/weeks playing and enjoying the games...
