Except for a few "rarities" I'm surprised at how low the used game sections are pricing the PS2 titles. Even the really good ones can be had for only a few dollars. I don't even remember PS1 games going this low when they were phasing them out.
What gives? Do you expect the prices to stay dirt cheap, and then slowly creep up like many of the PS1 games today? Right now the PS2 games offer awesome gaming value for the money.
