I own 2 complete copies of the 1986 version. It is still better than the restoration version in my opinion. Granted the new version has expansions and more style, but the board of the original is just great and strong.
Just bought this on your recommendation, and looking forward to playing it! Weirdly though there seems to be a 'new' version of the remake, titled 'Race to Adventure' which is missing quite a lot of the elements of this one. Would be interested if you've seen it at all?
Race to adventure is simplified. It just has the board treasure, dice, marbles, trees, and move cards. The bridges are chipboard instead of the plastic one you get in Curse. There have also been people on amazon who ordered Curse of Vulkar and got Race to Adventure instead.
