I wonder how many copies of this game ended up being sold?
A brand new copy sold on ebay 5 weeks ago for $40, so it appears that may be the going price for this game now (at least in new or very good condition)
Might be worth setting up an ebay search that notifies you whenever a new item appears. I doubt there is that much buying interest, so given some time and patience you can score a copy for < $10.
