I used to love the game and now it seems to have become stupidly rare, i have scoured shops all over my city and the internet and just cannot find it anywhere, does anybody know where i could buy a copy of this amazing game? I highly regret losing my original copy

There is no Sea Dogs 2.

There was a Sea Dogs 2 in development, but before it was released it changed name to http://en.wikipedia.org/wiki/Pirates_of_the_Caribbean_(video_game).
