As other people have likely said, bringing down the price of games is very unlikely due to the fact that games cost huge amounts of money. Everyone involved have to be paid and creating the game itself likely runs a company millions. It's stupid to think that they're just driving up prices because they feel like it. Think of it like this, would you rather pay $50 for a game with the average PS2/Wii quality to it, or $60 for a decent quality game. And before you say that there are worthless games for all systems, thanks for pointing out the obvious. That's why you read up about them or rent them before buying them.
Also, in the case of 'too expensive to pay new so buy used,' here's an idea; wait until the game to come down in price or save up. Yes, that sounds bad, but it's not like you'll die without the game. Used games are normally only $5 less anyways.
