It's just you... Video games are not worth 60 dollars to me anymore. 30 bucks tops...
The fact that you buy a game for 60 bucks, and then a month later the most you can get for it is 30 (if the game is good) means that the game was overpriced to begin with. I can't think of anything else found in the electronics section that loses 50% of its value in 1 month.
Video games should move to monthly subscription model if you ask me. Sega had the right idea with Sega Channel back in 1995.
