This is the most effective solution I've ever dealt with for antipiracy. As someone who's pirated software for a very long time, I've spent quite a bit of money, happily, through steam on video games. The benefits of buying through steam however, meet the requirements of most everyone in here. No CD to put in the tray, no keys to enter (if you buy a game online [which i recommend]), constantly updated, and most importantly, the purchase is tied to the account itself, so you can download your game infinite times to infinite machines as long as it's tied to your account. I have Audiosurf on three different machines, legally:)
