the things I would want to know are -
restored how? by who?
what did they do to restore the game?
the DE Simpsons can be picked up for around 2000 - 2200 then played for a year and probably resold for about what you paid
but if your going to buy a 2000 game put another 1000 or more dollars into it then your probably going to struggle to recoup your $$$ if and when you decide to sell,
as Marty said you need to go out and look, touch, take a few pics, play and ask ? as there are better 2000 dollar games out there than the DE Version of the Simpsons ( and don't buy the 1st title you come across.... thats a big rookie mistake)
