I don't know if anyone else would find this interesting/useful/helpful but I'd be interested in a section (or website link) that lists the games that have dropped or gained the most in value since the last guide has been out.

Also, a question about value. I know that game values can be very questionable/controversal, but how can Texas Chainsaw Massacre for the Atari 2600 be valued at only $30? I never see one going for less than $80-$100. Does ANYONE have a copy of the game that I can buy for $30, cause if you do I'd be interested.
