I'm always looking to support the industry by purchasing games at launch. But sometimes we can't always do that. Whether finances are tough and you just had to skip out some of those gems, it sometimes works out for you. Now, I don't ever recommend waiting on a title until it drops in price, it occasionally works that way.
GameFly is having one heck of a deal that is scheduled to end on 9/17. There are titles so cheap I picked up some for the other systems that I previously skipped out on.
