I'm not speaking of price discrimination at all. That would be Valve releasing a game at full price and then a week later putting it on sale for 25% off. This doesn't qualify as price discrimination because they're games that have been around. The value for buying earlier is that you've owned it and had the chance to use it reasonably longer than everyone who is getting it now.
I'm speaking of the specific market of fence-sitters who may have pirated the games but in this case are willing to throw a couple bucks at the games. Those people who who you never would have gotten money from otherwise.
