Okay, so I was hooked on Myst years ago, and even bought the iPhone version not too long ago. Frankly, it's showing its age and replaying the same game in a different format doesn't really do it for me either. It was great at the time since you were able to get amazing visuals despite graphics cards of the days back then were nowhere close to rendering that in real time. Today, in light of the Unreal3 engine etc. it feels kinda lame. Needless to say, fond memories of Myst turned into disappointment, and I am sure staying away from Riven.
