Hi Kim and Louis,
We loved 3 Skulls and have a review for it on our site, Mr. Bill\'s Adventureland
. Basically it is a parody or spoof on spaghetti westerns like "The Good, The Bad and The Ugly" or the John Wayne, Clint Eastwood type westerns.
I have heard of it going to a collector for as high as $300.00. It cost us over $40.00 a few years back to get a new boxed copy from Australia.
But, the good news might be the re-release of 3 Skulls from the developers at the time of (or shortly thereafter) the release of "The Westerner". Whether this actually happens or not is not certain, but Revistronic has mentioned the possibility.
