I bought Port Royale 1, but had to take it back because I couldn't get it working - on either my AthlonXP 1800+, or my wife's P4 laptop.
This is the only PC game I have had problems with since DOS days... I think I read somewhere online that it has some flaky programming, apparently makes it very picky what it will run on.
The original Pirates! was my fave, on C64 & Amiga. Never saw Gold until the PC, & there it kind of sucked.
And yes, there is a new "Sid Meier's Pirates!" coming out soon... they had a pre-order thing in the EB catalog...
