Sequels are a notoriously difficult thing to pull off, and Riven is an example of an unequivocal success. It took Myst’s design and built upon it rather than simply aping it, creating a completely fresh take on the existing concept. Beyond the continued storyline and identical control scheme, there is practically no resemblance between the two. It isn’t so much Myst II as it is Myst 2.0– a second release which corrects the shortcomings of an earlier version. Riven is a masterpiece, an example of what can happen when creators consider their past mistakes, aim high, and ignore the risks.
