meh, i'd understand the perspective that games are too expensive from an average dude with a playstation with no purchasing savvy, but the complaints from people who frequent this site are kinda ridiculous. Ofcourse if you walk into a game store and want to buy a game without doing research first, you're probably going to pay retail.
Sign up for sites like slickdeals or cheapassgamer, (or redflagdeals if you're canadian) and pay attention to gaming deals. There are LOTS of deals to be had by those who can be bothered to look. I own 15 ps3 games, and out of those there's only 4 I paid full price for. Try harder if you think ps3 games are too expensive.
